Multistage stochastic programming is a key technology for making decisions over time in an uncertain environment. One of the promising areas in which this technology is implementable, is medium term planning of electricity production and trading where decision makers are typically faced with uncertain parameters (such as future demands and market prices) that can be described by stochastic proc...

This paper presents a multi objective geometric programming model which determines the product`s selling price in two markets. We assume demand is a function of price and marketing expenditure in two markets. The cost of production is also assumed to be a function of demands in both markets. Our model is a posynomial function which is solved using Geometric Programming (GP). In our GP implement...

This paper presents researches on operation management for virtual enterprises (VEs). A virtual enterprise is a temporary alliance of member enterprises (MEs) formed to exploit fast-changing opportunities. During the operation of a virtual enterprise, its constituent member enterprises, which are geographically distributed and organizationally independent, collaborate with each other to execute...

Scientific workflows tend to be time consuming and data intensive, and today’s fast paced mobile culture does not afford researchers the luxury of neither sitting at a computer for days at a time, waiting for experiments. While business workflow research has addressed this issue, the solutions developed are not applicable to scientifc workflow systems, as the infrastructure of the two are not t...

Abstract: During recent years, optimal electrification of isolated offshore systems has become increasingly important and received extensive attention from the maritime industry. Especially with the introduction of electric propulsion, which has led to a total electrification of shipboard power systems known as all-electric ships (AESs), the need for more cost-effective and emission-aware solut...

Our objective is to develop generalized principles for grid operations centers that can be applied to specific domains. We focus on the domain of wireless telecommunications NOCs (WNOCs) as a starting point in this process. To address this problem, we focus specifically on the knowledge requirements for service-based decision support within wireless telecommunications. We use a Mission-PolicyMe...

Evaluating enterprise quality management system operation effectiveness, mining and extracting the fuzzy rules of affecting factors of enterprise quality management system operation effectiveness are important ways to solve practical quality problems and improve quality performance. This study integrates and combines statistical analysis methods of improved entropy method, catastrophe progressi...
