Bi-objective optimization of a multi-product multi-period three-echelon supply chain network consisting of manufacturing plants, distribution centers (DCs) each with uncertain services, and customer nodes is aimed in this paper. The two objectives are minimization of the total cost while maximizing the average number of products dispatched to customers. The decision variables are: (1) the numbe...

Investment managers are multi-objective decision-makers (DMs) who make portfolio decisions by maximizing profits and minimizing risks over a multi-period planning horizon. Portfolio decisions are complex multi-objective problems which include both tangible and intangible factors. We propose an integrated multi-objective framework for project portfolio selection with respect to both the profits ...

Let L(y) = 0 be a linear homogeneous ordinary di erential equation with polynomial coefcients. One of the general problems connected with such an equation is to nd all points a (ordinary or singular) and all formal power series ∑∞ n=0 cn(x − a) which satisfy L(y) = 0 and whose coe cient cn — considered as a function of n — has some ‘nice’ properties: for example, cn has an explicit representati...

The fundamental symmetric functions are EXk (equal to 1 if the sum of n input bits is exactly k), THk (the sum is at least k), and MODm,r (the sum is congruent to r modulo m). It is well known that all these functions and in fact any symmetric Boolean function have linear circuit size. Simple counting shows that the circuit complexity of computing n symmetric functions is Ω(n2−o(1)) for almost ...

This article addresses reinsurance decision making process, which involves the insurance company and the reinsurance company, and is negotiated through reinsurance intermediaries. The article proposes a decision flow to model the reinsurance design and selection process. In contrast to existing literature on pure proportional reinsurance or stop-loss reinsurance, this article focuses on the com...

This paper aims to extend fuzzy MULTIMOORA with linguistic reasoning and group decision-making (MULTIMOORA-FG). The new method consists of the three parts, namely the fuzzy Ratio System, the fuzzy Utopian Reference Point, and the fuzzy Full Multiplicative Form offering a robust comparison of alternatives against multiple objectives. In addition, MULTIMOORA-FG is designed to deal with triangular...

today, due to rising passenger expectations and other resource constraints, the airport managers and staff do to develop appropriate programs in order to optimize the allocation of the resources. gates and counters are important resources in airport. in this research problem of gate and counter for arrival flights is considered simultaneously and mathematical model is prepared. the objectives o...

qfd is a mechanism for translating the voice of customer into product through various stages of product planning, engineering and manufacturing that widely implemented in modern enterprises throughout the world. in parallel with welcoming to qfd, a lot of academic efforts have gone into improving and completing this method. now traditional methods for determining relative importance of factors ...
