Development of every society is incumbent upon energy sector’s technological and economic effectiveness. The electricity industry is a growing and needs to have a better performance to effectively cover the demand. The industry requires a balance between cost and efficiency through careful design and planning. In this paper, a two-stage stochastic programming model is presented for the design o...
Since third-party logistics (3PL) offers discounted prices for booking containers in advance, the container decisions are preferably made prior to realization of customer demand by companies with international trade business. When facing uncertain influenced various factors, it is significant make proper and order fulfillment plans minimize total cost, including cost penalty an unfulfilled orde...
The classic newsboy problem assumes the market demand to be a random variable. However, when the decision maker wants to expand the market share, he has to provide a subjective estimate of new market demand distribution due to the lack of historical data. Thus, randomness and uncertainty simultaneously appear in a newsboy problem. The aim of this work is to extend the analysis of the classic ne...
• Develop exact and approximation algorithms to solve the model. Derived closed-form solutions for three special cases. Conservative algorithm dominates large-scale instances. Seek best budget of uncertainty by cross validation method. This work studies a Robust Multi-product Newsvendor Model with Substitution (R-MNMS), where demand substitution rates are stochastic subject cardinality-constrai...
It is necessary to consider the impact of demand uncertainty to model the comprehensive approach for supply chain network design. This paper presents four echelons, multiple commodity, and strategic–tactical model for designing supply chain network. Uncertain demand, transportation mode selection with lead time configuration has been considered. A numerical example has been implemented to verif...
