A Systematic Approach to Composing and Optimizing Application Workflows

A Multi-Level Capacity Approach to the Hub and Spoke Network

The existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. Although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...

A Chance Constraint Approach to Multi Response Optimization Based on a Network Data Envelopment Analysis

In this paper, a novel approach for multi response optimization is presented. In the proposed approach, response variables in treatments combination occur with a certain probability. Moreover, we assume that each treatment has a network style. Because of the probabilistic nature of treatment combination, the proposed approach can compute the efficiency of each treatment under the desirable reli...

A location-allocation model in the multi-level supply chain with multi-objective evolutionary approach

In the current competitive conditions, all the manufacturers’ efforts are focused on increasing the customer satisfaction as well as reducing the production and delivery costs; thus, there is an increasing concentration on the structure and principles of supply chain (SC). Accordingly, the present research investigated simultaneous optimization of the total costs of a chain and customer satisfa...

A Multi-Perspective Approach for Modeling Workflows

1. Introduction With the recent advance in information technologies, such as the Internet, organisations face, at different levels, several types of challenges. At the external level, organisations have to remain competitive, when offering services to their customers and satisfying these customers' needs. At the internal level, organisations have to be able to react quickly and efficiently to t...
