⎯There have been many studies on two-stage supply models. Because supply chains are increasingly more complicated, this study considers the three-stage supply chain configurations which involve multiple companies at each stage and each company at the upstream stages can supply two or more customers. The coordination mechanisms for the members along the chain are achieved in the following two as...

The purpose of this paper is to illustrate componentbased visual simulation model development using the Visual Simulation Environment (VSE) software product. Two libraries are presented: clock library and distribution library. The clock library provides reusable model components for representing date and time in the Gregorian calendar. The distribution library provides reusable model components...

In order to this survey, lee  & Gough & Moses & Sinelane theories and for survey of effective factors on HR, Stainer and Christopher theories have been used with ten phrases as theorical framework.Statistical ...

Risk theory refers to a body of techniques to model and measure the risk associated with a portfolio of insurance contracts. A first approach consists in modeling the distribution of total claims over a fixed period of time using the classical collective model of risk theory. A second input of interest to the actuary is the evolution of the surplus of the insurance company over many periods of ...

The transportation problems are primarily concerned with the optimal way in which products produced at different plants (supply origins) are transported to a number of warehouses or customers (demand destinations). The objective in a transportation problem is to fully satisfy the destination requirements within the operating production capacity constraints at the minimum possible cost. The obje...
