Collaboration for a two-echelon supply chain in the pulp and paper industry : the use of incentives to increase profit

2010-01-06, Lehoux, Nadia, D'Amours, Sophie, Frein, Yannick, Langevin, André, Penz, Bernard

In our research, we study the case of a pulp and paper producer who decides to establish a partnership with one buyer. Using two different types of relationship, namely a traditional system without any collaboration scheme and Collaborative Planning, Forecasting and Replenishment, we develop decision models describing the producer and the buyer planning processes. We also identify which approach is more profitable for each actor as well as for the network, based on real costs and parameters obtained from the industrial case. We then test how different incentives can improve the traditional system and provide higher gains for each partner. Our results show that using incentives increases the system's profit by up to 4% if parameters are well defined.

Generic mechanisms for coordinating operations and sharing financial benefits in collaborative logistics

2010-01-01, Rönnqvist, Mikael, Lehoux, Nadia, Audy, Jean-François., D'Amours, Sophie

Collaborative logistics is increasingly emerging as a new opportunity for cost reduction through internal and cross chains coordination. This paper presents different coordination mechanisms to support collaborative logistics. These mechanisms are differentiated by their planning function, their sharing approach and the information, decision and financial flows. Often, the logistics planning is run first, and secondly, the sharing is set on the basis of the plan. However, recently, new approaches have been proposed where both the logistics plan and the sharing are optimized simultaneously. Constraints on the financial flows also introduce specificities to the coordination mechanisms and these are described and discussed. Finally, the proposed coordination mechanisms are used to describe a series of research and applied projects in which collaborative logistics has been implemented.

A framework for an efficient implementation of logistics collaborations

2010-12-07, Rönnqvist, Mikael, Lehoux, Nadia, Audy, Jean-François., D'Amours, Sophie

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 activities will be planned and executed, who will take the leadership of the collaboration, and how benefits will be shared. In this article, we explain how to efficiently build and manage inter-firm relationships. Moreover, we propose five coordination mechanisms that contribute to ensure information sharing, the coordination of logistics activities, and the sharing of benefits. Case studies are used to demonstrate the utility of the framework.

Methodology for assessing collaboration strategies and incentives in the pulp and paper industry

2011, Lehoux, Nadia, D'Amours, Sophie, Langevin, André

Under current economic conditions, several companies have decided to implement collaborations with their suppliers, distributors, and retailers, in order to share products and information efficiently as well as reduce their operational costs. Even traditional industries such as the forest industry are now seeking for new business relationships to outperform the competition. In this article, we propose a case study of collaboration between a pulp and paper producer and a wholesaler. In particular, we describe a methodology used to compare different collaborative approaches. We show that this methodology is useful to take multiple operational parameters and constraints into account, as well as to update planning decisions over time. We also discuss the different results obtained for the case study. We demonstrate that collaborative approaches such as CPFR and VMI may reduce network costs, but the savings obtained with these strategies must be distributed fairly. Furthermore, we analyze the use of several incentives to increase the value and strength of the collaboration.

Supply chain modelling frameworks for forest products industry : a systematic literature review

2014-02-01, Vahid, Saba, Frayret, Jean-Marc, Lehoux, Nadia, Santa-Eulalia, Luis-Antonio, D'Amours, Sophie, Venkatadri, U. (Uday)

Considering the economic importance of forest products industries in Canada, there has been an increasing interest to study the operations and interactions of all the relevant entities involved in its supply chain (SC). The forest products industry has a set of specific SC characteristics to meet the needs of its final consumers. While a growing number of mathematical and simulation models are being presented for the SC in this sector, an integrated formal structure is evidently required for guiding the development of and evaluating these models. Therefore, in this research, we systematically review and identify existing frameworks for modelling SCs with the interest of highlighting the ones relevant to the forest products SCs. While we find no framework specific to the forest products industry, we identify a number of existing frameworks that could be customized to represent the industry's SC.

Issues and experiences in logistics collaboration

2009, Rönnqvist, Mikael, Lehoux, Nadia, Audy, Jean-François., D'Amours, Sophie

Collaborative logistics is becoming more important in today’s industry. This is driven by increased environmental concerns, improved efficiency through collaborative planning supporting resources sharing and new business models implementation. This paper explores collaborative logistics and reports on business applications within the forest products industry in Sweden and Canada. It first describes current opportunities in collaborative planning. It then discusses issues related to building the coalition as well as sharing resources and benefits. Three business cases are described and used to support the discussion around these main issues. Finally, different challenges are detailed, opening new paths for researchers in the field.

Value creation network of canadian wood fibre

2012-07-01, Marier, Philippe, Lehoux, Nadia, Beaulieu, Jean, D'Amours, Sophie, Ouellet, Denis

In this paper, we describe the Canadian wood fibre value network by explaining what constitutes a value creation network, how to model this kind of network, and how it can be managed efficiently. Research for the forest industry conducted by national and international researchers as well as by Forac students are also provided. The paper finally reviews different technologies that could be useful to forest products companies in order to facilitate their decision-making process.

Hvorfor samarbeide?

2011-05-01, Rönnqvist, Mikael, Lehoux, Nadia, Audy, Jean-François., D'Amours, Sophie

Mange bedrifter ser på samarbeid som en mulighet til å styrke sin egen konkurransekraft, få tilgang til nye markeder og innfri operasjonelle, samfunnsmessige og miljørelaterte krav og restriksjoner. Samtidig har hver enkelt bedrift sine egne målsettinger som danner grunnlag for bedriftens planer og beslutninger. Derfor er det viktig å finne ut hvordan de ulike forretningsenhetene vil fungere sammen, og hvilken verdi samarbeidet vil ha. Ved samarbeid om logistikk er det spesielt viktig å identifisere hvordan logistikkaktivitetene skal planlegges og gjennomføres, og hvordan gevinsten skal fordeles. I skogindustrien konkurrerer bedriftene om salg av sine produkter på markedet, men også om anskaffelse av de ulike tømmermaterialene de trenger. Logistikk knyttet til forsyning og leveranse av ferdige produkter er et viktig ledd i verdikjeden. Selv om flere skogbedrifter ofte driver sin virksomhet i samme område eller marked, er det ikke vanlig med samarbeid mellom to eller flere bedrifter. I denne artikkelen presenteres tre kasusstudier fra skogindustrien der slike samarbeid analyseres, testes og - i to av tilfellene - iverksettes. En vanlig tilnærming har vært å bruke vanlige, driftsbaserte forskningsmodeller og metoder, deriblant spillteori. Resultatet viser at samarbeid kan gi store fordeler, men det er stor variasjon i erfaring og bruk av resultatene. Prosessen har også vist at vi mangler metodikk som dekker reelle behov i bransjen - derfor presenterer vi her en enkel metodikk som kan danne utgangspunkt for et samarbeid.
