Stability Contracts between Retailers and Suppliers Using Quantity and Time Constraints
In this paper, a relationship managed by contracts between a supplier and a retailer is considered. In these contracts, constraints on the order amount are usually emphasized. Additionally, it is proposed to use another type of constraint, based on the frequency of the orders. A contract can be split in two parts: the amount constraints, and the frequency constraints. These frequency constraints are called dynamic time windows, and they are formally defined as mathematical constraints in an integer linear program. Numerous tests are distributed into two experiments, which help to understand the model. Finally, it is shown that the two parts of a given contract (amount and frequency) are hugely linked. Being more constrained on a single part of a contract involves many effects on the second part of the contract. For example, if a single part of a contract is tightened, the second part of the contract can be tightened, in the same way, and without any cost increase.

Aligning Key Success Factors to ERP Implementation Strategy: Learning from a Case-Study
These last years, we can observe that most of companies implemented an ERP system but many of them fail. Much of research that has been conducted in this field, focus on KSFs. We have noticed that confronting those KSFs to ERP implementation strategies seems quiet fecund. So provide in this article a brief overview of the literature dealing with key success factors related to an ERP implementation project to better cope with the field, then come out with a framework analyzing these KSFs depending on implementation strategies. Then we study a case of an ERP implementa-tion project in a company operating in the automotive industry, with a quail-metric methodology, to better understand the reasons of ERP implementation projects success or failure.

The Relationship between Trust and Inventory Replenishment in Supplier-Customer Dyad: An Experimental Study
Trust has been identified as a significant role-playing factor, which guards supply chains against high inventories and poor customer services. Previous research addressed trust in supply chain mostly with the aid of surveys, interviews and field data analysis. Using an extended version of the Beer distribution Game, this paper examines the impact of trust on inventory replenishment indicators in dyadic supply chain. To measure trust, a trust measurement mechanism is proposed. This trust measurement mechanism is based on questionnaires to be filled at regular time intervals by suppliers and customers during the experiment. Correlation analysis is preformed to assess the relationship between trust and inventory replenishment indicators. Results show that trust in supplier is negatively associated with
average order quantity and time between orders for customers. Surprisingly, no significant correlation is found between trust in customer and inventory replenishment indicators for suppliers. However, both trust types seem to play a role in the supplier-customer dyad dynamics.
