In today’s competitive market, those producers who can quickly adapt themselves todiverse demands of customers are successful. Therefore, in order to satisfy these demands of market, Mixed-model assembly line (MMAL) has an increasing growth in industry. A mixed-model assembly line (MMAL) is a type of production line in which varieties of products with common base characteristics are assembled o...

The arrival of social and collaborative software applications (e.g. Facebook, Hyves, and LinkedIn), known as Web 2.0 applications, has provided an opportunity for customers to express their opinions and share their knowledge and thoughts with others. While customers use Web 2.0 applications on daily basis, companies are struggling to embrace fully functioning Web 2.0 applications for their busi...

In this paper we analyze the effect of including price competition into a classical (market entrant’s) competitive location problem. The multinomial logit approach is applied to model the decision process of utility maximizing customers. We provide complexity results and show that, given the locations of all facilities, a fixed-point iteration approach that has previously been introduced in the...

We investigate the use of dimensionality reduction to improve the performance for a new class of data analysis software called “recommender systems”. Recommender systems apply knowledge discovery techniques to the problem of making personalized product recommendations during a live customer interaction. The tremendous growth of customers and products in recent years poses some key challenges fo...

One of the most severe manifestations of poor quality of software products occurs when a customer “escalates” a defect: an escalation is triggered when a defect significantly impacts a customer's operations. Escalated defects are then quickly resolved, at a high cost, outside of the general product release engineering cycle. While the software vendor and its customers often detect and report de...

This master thesis deals with a special variant of the Vehicle Routing Problem (VRP), where there are many customers per road segment. This kind of VRP arises in many real-life situations, e.g. mail delivery and garbage collection. VRP solvers are part of most Decision Support Systems (DSS) used by companies in this business sector. In an operational setting, it is often more important to get a...

With the generalization of the Cloud, software providers can distribute their software as a service without investing in large infrastructure. However, without an effective resource allocation method, their operation cost can grow quickly, hindering the profitability of the service. This is the case for BPM as a Service providers that want to handle hundreds of customers with a given quality of...

In this work we consider the capacity and distance constrained plant location problem (CDCPLP). This problem is a type of location and routing problem, in which a set of customers has to be assigned cost efficiently to plants that can be opened at discrete locations. Customers are then served from the associated plants by round-trips of plant’s vehicles. Since the capacity of the plant and the ...

Recently business process management has received a lot of attentions because of its potential to dramatically improve business efficiency. This paper describes an end-to-end scenario for the business process execution and monitoring for the JIT (Just In Time) schedule execution. JIT is a manufacturing method developed in Japan and later quickly spread into other countries. The purpose of JIT i...
