Virtual transportation manager a decision support system for collaboratie forest transportation by Jean-François Audy( )

4 editions published in 2013 in English and held by 6 WorldCat member libraries worldwide

Transportation operations account for a significant part of wood procurement costs. In recent years in Canada, a number of research initiatives have been devoted to forest transportation planning methods as a mean of acheiving cost reduction. Moreover, literature on freight transportation identifies inter-firm collaboration in transportation planning as a way to attain further cost-savings. Typically in Canada, many decision makers are involved in forest transportation at a regional level. This article presents a decision support system supporting collaborative transportation among these decision makers. More precisely, collaboration takes place in the routing of forest trucks, i.e. the determinatin of the set of routes to deliver transportation requests specified by the decision makers. The main components of the system as well as how transportation collaboration is organized with the system are detailed. The routing problem addressed and the solution method proposed are described. An industrial case study in which the system was tested is presented with the results obtained. Details about the actual outcome of the case study complete the discussion.--Document
Inter-firm collaboration in transportation by Jean-François Audy( )

2 editions published in 2013 in English and held by 5 WorldCat member libraries worldwide

Dans la littérature académique et professionnelle relative au transport de marchandise, il y a longtemps que les méthodes de planification avancées ont été identifiées comme un moyen de dégager des économies grâce à une efficacité accrue des opérations de transport. Plus récemment, la collaboration interentreprises dans la planification du transport a été étudiée comme une source de gain supplémentaire en efficacité et, par conséquent, une opportunité pour dégager de nouvelles économies pour les collaborateurs. Cependant, la mise en œuvre d'une collaboration interentreprises en transports soulève un certain nombre d'enjeux. Cette thèse aborde trois thèmes centraux de la collaboration interentreprises et démontre les contributions via des études de cas dans l'industrie forestière et du meuble. Premièrement, les moyens technologiques pour soutenir une collaboration en planification du transport sont étudiés. Un système d'aide à la décision supportant la collaboration en transport forestier est présenté. Deuxièmement, le partage entre les collaborateurs du coût commun en transport est étudié. Une méthode de répartition du coût de transport tenant compte de l'impact - l'augmentation du coût de transport - des exigences inégales entre des collaborateurs est proposée. Troisièmement, la création de groupes collaboratifs - des coalitions - dans un ensemble de collaborateurs potentiel est étudiée. Un modèle réseau pour la formation d'une coalition selon les intérêts d'un sous-ensemble de collaborateurs adoptant ou pas un comportement opportuniste est détaillé. De plus, pour soutenir l'étude des thèmes précédents, la thèse comprend deux revues de la littérature. Premièrement, une revue sur les méthodes de planification et les systèmes d'aide à la décision en transport forestier est présenté. Deuxièmement, à travers la proposition d'un cadre pour créer et gérer une collaboration en transport et, plus généralement en logistique, une revue de travaux sur le transport et la logistique collaborative est offerte

A framework for an efficient implementation of logistics collaborations( Book )

3 editions published in 2010 in English and held by 4 WorldCat member libraries worldwide

In order to beat the competition, access new markets and respect operational, social and environmental constraints, enterprises establish collaborations with many other business entities. Furthermore, with costs and information sharing, organizations have the opportunity to optimize their logistics activities. However, each enterprise has its own objectives and typically makes its own planning decisions to meet these objectives. Therefore, it becomes crucial to determine how business entities will work together as well as the value of the collaboration. Specifically, it is necessary to identify how logistics activites will be planned and executed, who will take the leadership of the collaboration and how benefits will be shared. In the article, the authors explain how to efficiently build and manage inter-firms relationships. The authors also propose five coordination mechanisms that contribute to ensure information sharing, the coordination of logistics activities and the share of benefits. Case studies are used to demonstrate the utility of the framework.--Document
Analysis of building coalitions and savings sharing : application to forest transportation by Jean-François Audy( Book )

3 editions published in 2009 in English and held by 4 WorldCat member libraries worldwide

Transportation is an important part of the forestry supply chain. Typically, several forest companies operate in the same region. However, coordination of the wood flows between two or more companies is rare. Questions about how the potential savings should be divided among a group of collaborating companies and how the collaborating groups should be formed have been identified. In this paper the authors study these two questions in a specific context: among the potential collaborating companies, a subset, denoted the leadings companies, performs the collaborative transportation planning on behalf of the others. They use the concept of a business model to detail such context. Based on the literature on network formation where potential savings are modelled by a cooperative game, four business models in four different scenarios of leading companies are explored. A case study including eight forest companies is described and analysed.--Includes text from document
Deployment by a Shipper of a Collaborative Approach with its Carriers by Guillermo Conte Moraga( )

1 edition published in 2019 in English and held by 4 WorldCat member libraries worldwide

One important challenge in the forestry industry is to reduce the overall transportation cost between suppliers and clients. The forestry industry moves large quantities of wood from harvest areas to terminals and mills. When many organizations are involved, a collaboration between the suppliers as well as an efficient use of allocations, achieve better solutions. Allocations are typically based on direct flows between supply and demand nodes. However, better solutions can be found when return trip routes are used. These are difficult to find when there are several stakeholders involved, but adding information from harvest production can establish better collaboration between suppliers as well as more efficient plans. The purpose of this project is to define a model that can resolve the delivery from multidepots to multi-customers, in a multi-period of time, minimizing the cost of transport for different types of timber. To propose a novel method for scenarios where the clients only receive products from pre-determined suppliers. Also, it analyzes different methods of transport payment for backhaul routes, in order to establish a mechanism that encourages the transport suppliers to use collaborative transport. We describe results obtained with a pulp and paper company in Quebec, Canada
L'amélioration de la prévisibilité des approvisionnements forestiers by Etienne Thivierge-Robitaille( )

1 edition published in 2019 in French and held by 4 WorldCat member libraries worldwide

Au cours des dernières années, le manque de prévisibilité des approvisionnements en bois a été identifié comme un facteur qui entrave la compétitivité du secteur forestier. Alors que plusieurs entités croient que le changement de régime forestier québécois de 2013 est l'un des facteurs ayant mené à cette affirmation, il semble que la présence de plus en plus marquée d'une relation client fournisseur dans les approvisionnements forestiers soit aussi partiellement responsable. La problématique du manque de prévisibilité des approvisionnements est composée de deux éléments. D'abord, aucune définition reconnue de la prévisibilité de l'approvisionnement en bois n'a été proposée par la communauté scientifique. De plus, dans la pratique, les intervenants ne semblent pas partager une compréhension commune des origines du manque de prévisibilité. En l'absence de connaissance sur les causes réelles, il s'avère difficile de proposer des recommandations. À ce jour, aucune étude ne s'est penchée sur la problématique du manque de prévisibilité des approvisionnements forestiers. Ce travail vise à combler cette lacune. Une série de 20 entrevues impliquant des intervenants de la chaîne d'approvisionnement forestier a été réalisée. En complément, un cas d'étude auprès d'une usine de pâtes et papiers du Québec a permis d'étudier la prévisibilité de l'approvisionnement en bois dans le cadre des pratiques d'achats au niveau opérationnel. Une méthode d'évaluation basée sur le processus de collecte de données en place, la politique d'allocation des contrats et les méthodes de prévision des acheteurs a été appliquée. Sur la base de nos résultats, nous définissons la prévisibilité des approvisionnements forestiers comme étant la capacité à anticiper l'offre de bois dans le temps, avec un certain degré de précision. Par la suite, les entrevues et l'étude de cas ont permis d'identifier 37 causes et 17 sources du manque de prévisibilité. Ces éléments ont été regroupés en cinq catégories. Enfin, cinq causes spécifiques à la gestion des fournisseurs et au suivi des ententes contractuelles sont à la base des recommandations visant à améliorer la prévisibilité dans un contexte d'achats de matière ligneuse. Quatre des recommandations proposées suggèrent une allocation de contrats basée sur les performances antérieures des fournisseurs. Une recommandation au niveau du suivi de la qualité des prévisions est aussi proposée
Selection of Wood Supply Contracts to Reduce Cost in the Presence of Risks in Procurement Planning by Ali Rahimi( )

1 edition published in 2020 in English and held by 3 WorldCat member libraries worldwide

Procurement activities in the pulp and paper industry account for an important part of the overall supply chain cost. Procurement decision-makers plan for the required wood supply up to one year in advance to guarantee the supply volume for the continuous production process at their mill. Regular, flexible and option contracts with suppliers in different groups are available. Suppliers are grouped based on common characteristics such as forestland ownership. However, during the execution of the plan, sourcing risks affect procurement operations. If risks are not integrated into the procurement planning process, mitigating their impact is likely to be expensive and complicated. Additional expensive ad hoc contracts might be required to compensate for the lack of deliveries. To tackle this problem, the first project of this thesis demonstrates the development of a deterministic mathematical model of procurement operations. The objective of the model is to propose an annual procurement plan to minimize the total cost of procurement operations. The operations are subject to constraints such as the minimum share of supply for each group of suppliers, inventory target levels, demand, woodyard capacity, and chipping process capacity. The decisions are related to the selection of sourcing contracts, woodyards opening, and wood supply flow. In the second project, an evaluation of the procurement plan from the deterministic model from project one is performed by using a Monte Carlo simulation approach. Three different strategies are compared as fixed, flexible, and a mix of both contracts. The simulation approach in this project evaluates the performance of the plan by the expected value and variability of the total cost when the plan is executed during the planning horizon. In the third project, a two-stage stochastic programming approach is used to provide a reliable procurement plan. The objective of the model is to minimize the expected cost of the procurement plan in the presence of different scenarios generated based on sourcing risks. First-stage decisions are the selection of contracts in the first period and the opening of woodyards. Second-stage decisions concern the selection of contracts starting after the first period, flow, inventory, and chipping process production. The case study used in this thesis was inspired by Domtar, which is a pulp and paper company located in Quebec, Canada. The results of three projects in this doctoral dissertation support decision-makers to reduce the human limitation in performing complicated procurement planning. The developed mathematical models provide a basis to evaluate the selected procurement strategy. This task is nearly impossible with current approaches in the company, as the evaluations require the formulation of v sourcing risks. The stochastic programming approach shows better financial results comparing to deterministic planning, with low variability in mitigating the impact of risks
Backhauling optimization for a wood recycling company by Maxime Leclerc( )

1 edition published in 2020 in French and held by 3 WorldCat member libraries worldwide

Transportation costs represent a large portion of the operation costs for wood recycling companies. The problem we study is the transportation with backhaul problem in which a company must decide how to connect its supply and demand points using routes. In this master’s thesis, the problem solved is a special case of the transportation problem where the producer only has one mill. This special case is rarely studied in the scientific literature. We use a linear programming model to solve these problems. We present results obtained when applying this approach to data from a wood recycling company. We investigate the effect of the planning time horizon by comparing yearly transportation planning against weekly planning. We also compare the effect of different distance calculations, different types of trucks and different optimization goals. The results show 42% in traveled time savings for yearly planning and 36% in savings for weekly planning. We also analyse the distribution of the backhaul savings among a set of carriers and report that 49% of the savings involved the recycling company’s prioritized carrier. When we add constraints on truck types that can perform backhauls, savings drop to 17%. These constraints result from the fact that wood recycling companies handle different categories of materials and therefore require specific truck configurations. Finally, an analysis of the recycling company’s transportation costs and revenues show that our model has the potential to substantially increase transportation revenues

Modélisation et optimisation multi-niveaux du transport forestier by Kamel Moad( )

1 edition published in 2016 in French and held by 1 WorldCat member library worldwide

The present manuscript tackles the supply chain forest transportation problem in the context of forestry primary industry. In this context, several risks may affect the forest supply chain: the unpredictable weather conditions (tree falling provoked by major storms); sanitary emergencies (tree pest and diseases); and, diverse commercial circumstances (the variability of market demands). The aforementioned issues motivate the diverse forest sector protagonists (entrepreneurs, forest operators and drivers) to seek support for improving their logistic operations. The aim of this effort is to improve the service quality (offer-demand agreement) diminishing in this way the total costs. Therefore, the main goal of this thesis is the proposal of a novel management model which improves forest-to-mill transport performance. At the same time, the proposed model accounts for the forest sector manners and constraints. The contribution of this thesis is threefold: first a transportation model is developed, later on the transport planning is managed, and finally an optimization procedure is proposed.The thesis results propose a hierarchical planning for the forestry transportation. Two decision levels are suggested: tactic and operational. At a tactic level, a multi-period optimization is considered. The multi-period optimization strategy meets the customer supply demands while minimizes the global transportation activity. Such strategy takes into account the restrictions of the total available transportation means. Moreover, at this level the activity balancing politics may be developed, as well as subcontractors coordination between transport companies. On the other hand, at the operational level, the tactic planning assigned for each transporter is divided so an optimization of the fleet's transport assignation is done considering the vehicles constraints.The decision process is modelled as a Mixed Linear Programming formulation. The application considers a data set coming from the industry settled at the Aquitaine region in France. The results have shown a significant improvement on the transport capabilities with respect to the conventional transport practices.It is worth to mention that the decision models were designed such that they may be adapted to different context either collaborative or not. In both cases, the tactic planning has a generic purpose, in other words, it is independent of the kind of organization involved, whereas specific organizations are taken into account when planning actors' activities at the operational level
