We propose a nonparametric model for global cost minimization as a framework for optimal allocation of a firm’s output target across multiple locations, taking account of differences in input prices and technologies across locations. This should be useful for firms planning production sites within a country and for foreign direct investment decisions by multi-national firms. Two illustrative ex...

In this study, we compare the performance of trading strategies based on possibly mis-specified mathematical models with a trading strategy based on a technical trading rule. In both cases, the trader attempts to predict a change in the drift of the stock return occurring at an unknown time.We explicitly compute the trader’s expected logarithmic utility of wealth for the various trading strateg...

A layout plan for a manufacturing system that is designed without any facility constraints will most likely be infeasible when confronted with reality. Additionally, considering land available building industrial plants limited and its cost high, it necessary to investigate the planning of two multi-floor facilities. To address these shortages in scientific literature, we focus on double-floor ...

Due to economy of scale, it is suggested that individual users, in order to save costs, should join a cooperation rather than acting on their own. However, a challenge for individuals when cooperating with others is that every member of the cooperation has to agree on how to allocate the common costs among members, otherwise the cooperation cannot be realised. Taken this issue into account, we ...

data envelopment analysis (dea) is a technique based on mathematical programming for evaluating the efficiency of homogeneous decision making units (dmus). in this technique, inefficient dmus are projected onto the frontier, which was constructed by the best performers. centralized resource allocation (cra) is a method in which all dmus are projected onto the efficient frontier through solving ...

Catholic Relief Services, a not-for-profit agency that funds development programs and humanitarian relief efforts throughout the world, faces a challenging budget-allocation problem annually. We developed a mathematical model and a spreadsheet tool that allocates available funds based on the impact these investments will have in different countries. The model ensures a fair allocation to countr...

An alternative mathematical expression for the co-channel interference probability is used, in order to calculate the cellular mobile radio system capacity and to construct a set of compatibility constraints needed for the development of fully adaptive channel allocation (FACA) strategies. The development of such channel allocation techniques becomes a main thrust for the system engineers in or...
