The aim of this paper is to develop an optimization model for quality improvement by considering quality investment in rework policies and supply chain profit sharing. To improve product’s quality, the decision of process target and its tolerance is important since it directly affects the defective rate, manufacturing cost, and loss to customer due to the deviation of product from its specifica...

the goal of this paper is to show how the concept of fuzzy logic can be used to establish a degree to which an investment project belongs to a class of risk. also, the probability of the fuzzy event is presented and is ap-plied to calculate the probability of the fuzzy event “the project x is a good investment”. this process has to enable the decision maker to compare several alternative invest...

 Imperfect production processes lead to imperfect products and decrease the profit of a business. Improvement in the production process by increasing the investment cost will decrease the defective percentage of items. This study develops an EPQ model with investments on imperfect production processes under limited capital. An algorithm is developed to derive the replenishment and investment p...

This paper proposes a general model to value different strategies to enter a market, comparing alternative sequential segmentation paths to simultaneous investment in all segments. This general model also allows demand to evolve accordingly to an endogenous regimeswitching process, under which it can behave differently before and after investment. It is shown how uncertainty, revenues and inves...

Central and Eastern Europe countries are in the political and economic transitional process of merging with the European Union. How has foreign investment already transformed these countries’ economic sectors and how will it affect the national economies in terms of capitalization across economic sectors in the near future? Our prime consideration is portfolio investment impact on the dynamics ...

As the front-end to product and system lifecycles, research and development activities serve as engines of value creation. By nature, though, R&D involves significant uncertainty. As such, it often is viewed as an investment problem, whereby funds are invested in ventures under risk, with the hope of achieving future value. This paper investigates the use of organizational simulation to analyze...
