Errors in order forecasts are a salient source of inefficiencies in retail supply chains. Many operational decisions made by suppliers hinge on order forecasts, which typically are based solely on either order or point-of-sale (POS) history. Using a discrete-time formulation, this research demonstrates that if a supplier knows that a retailer is using a base stock policy, it should use that kno...

In this paper the application of rule mining in order to review the effective factors on supplier selection is reviewed in the following three sections 1) criteria selecting and information gathering 2) performing association rule mining 3) validation and constituting rule base. Afterwards a few of applications of rule base is explained. Then, a numerical example is presented and analyzed by Cl...

In this paper, we develop a green handover protocol in two-tier OFDMA macrocell-femtocell networks. To improve the energy efficiency of femtocell base station, the proposed green handover protocol can intelligently switch on its radio communication and associated processing, or called as “wake up” from the idle mode, if the remainder data of a mobile host can be completely uploaded through the ...

We consider a make-to-stock supplier who operates a production facility with limited capacity. The supplier receives orders from customers belonging to several demand classes. Some of the customer classes share advance demand information with the supplier by announcing their orders ahead of their due date. However, this advance demand information is not perfect because the customer may decide t...

We investigate here antecedents and consequences of supplier integration (black-box and gray-box) in product development activities. Antecedents include embeddedness with suppliers, supply base rationalization, and supplier selection based on product development capabilities. Product innovation and quality are modeled as returns of supplier integration in product development. We also assess the...

The objective of this paper is to study an integrated two-supplier supply chain whose suppliers are unreliable. An unreliable supplier is alternative between available (ON) and unavailable (OFF) states which are considered to be independent exponential variables. The suppliers apply a continuous review policy and the retailer uses an adapted continuous review base on an(R,Q) policy. Transportat...

Although tyre expenses can be a significant component of the operating costs in civil engineering construction (CEC) companies, there are few studies investigating how the CEC industry can benefit by implementing specific tyre purchasing policies. The research aimed to highlight the expenditure on tyres, the factors affecting these, and how specific purchasing policies can impact on the total c...

The global subject of the thesis is in line with the continuous improvement method within industrial company. Our target is to analyse what would be the answer coming from the purchasing organization to interface with New Project Development (NPD). Basically, to insure their future industrial company must integrate their supplier base in NPD phases. Our study is based around six main axes : the...
