in present competitive business environment, learning organization is an important competitive advantage. along the time with its changes, cause the organization has to pay more attention to learning for improving their quality process more than the past. these changes has affected on different organizations, such as conservation environment organization (ceo). according to the monitoring role ...

Investment casting is a versatile manufacturing process to produce high quality parts with high dimensional accuracy. The process begins with the manufacture of wax patterns. The dimensional accuracy of the model affects the quality of the finished part. The present study investigated the control and optimization of dimensional deviations in wax patterns. A mold for an H-shaped wax pattern was ...

Previous studies in the issue of inventory models with imperfect quality assumed the defectives could be sold in a batch by the end of the inspection process and the manufacturing systems were push systems. However, the above assumptions may not be true in the pull system in which buyer is powerful. Therefore, in this paper, we develop a new inventory model for items with imperfect quality and ...

I model the interaction between dynamic decision making and social learning about new technologies in driving industry takeoff and productivity growth. Learning about the use of new technologies is an important factor in economic growth, but I demonstrate that anticipated social learning can lead to a free-riding dynamic in scenarios with high uncertainty. I consider the empirical setting of hy...

Asymmetric information potentially leads to adverse selection, market inefficiency, and market failure. To mitigate these problems, market designers rely on different policies. Some adopt reputation policies in which they certify high-quality users and help them signal their quality; others provide marketplace guarantee policies and, in the process, prevent low-quality users from participating....

This article develops an integrated JIT lot-splitting model for a single supplier and a single buyer. In this model we consider reduction of setup time, and the optimal lot size are obtained due to reduced setup time in the context of joint optimization for both buyer and supplier, under deterministic condition with a single product. Two cases are discussed: Single Delivery (SD) case, and Multi...

In our daily lives we often make decisions on the basis of information that we’ve received from parties who are affected by the outcome of those decisions. In these situations, the interested party may have an incentive to manipulate our choice by strategically revealing information. Milgrom and Roberts (1986) provided a classic model of such a situation. In what they call a persuasion game, an...
