Fuzzy modelling of static system optimum traffic assignment problem having multi origin-destination pair

Traffic congestion is an unpreventable problem to avoid in a transportation network and it has negative effects on traffic accident, time wasting, traffic delay and safety problem. Besides, in transportation networks, drivers do not want to deal with traffic jam while traversing between specified origin-destination pair. Therefore, traffic assignment (TA) is imperative to improve traffic management, transportation safety, time, and cost savings. System Optimum Traffic Assignment Problem (SOTAP) is a kind of TA model which aims to minimize the total system travel time on the network, and satisfies the flow conservation constraints. To model the SOTAP more realistically, the imprecise parameters can be taken as fuzzy. Therefore, in this paper, we focus on converting the conventional SOTAP to a fuzzy quadratic programming problem (QPP) which is named System Optimum Fuzzy Traffic Assignment Problem (SOFTAP). Here, link travel time is expressed with BPR function as generally used in the literature by converting to fuzzy except link-dependent parameters. Thus, the nonlinear objective function of SOFTAP is expressed in terms of fuzzy link flows and fuzzy link travel times. A solution approach from the literature is modified to the reconstructed SOFTAP.

Reengineering of materials management system: A case study

A business process reengineering (BPR) project relating to the materials management function of a cement manufacturing plant is presented in this paper. The BPR project evolved out of an organisation development (OD) intervention initiative. Such an intervention aimed at improving value innovation capability of materials management professionals of a large cement manufacturing plant in India. The proposition here is that the value metrics relate to inside-in value innovations in order to deliver inside-out value to the customers in the face of fierce competition in Indian Cement industry. Materials of all types used in a cement plant constitute 60–70% of the total cost and hence the effective operations of procurement and inventory are the critical success factors for strategic value innovations and thereby competitiveness. The primary emphasis in this project was on learning and implementation, by creating an urgency for instilling responsible leadership and building organic partnership through knowledge networking.
