Conjoint analysis is a statistical technique used to elicit partworth utilities for product attributes from consumers to aid in the evaluation of market potential for new products. The objective of the share-of-choice problem (a common approach to new product design) is to find the design that...

In this paper, we investigate a manpower planning problem with single employee type over a long planning horizon. The dynamic demand for manpower must be fulfilled by allocating enough number of employees and each employee has a minimal employment period. A cost objective is concerned where the...

We develop a branch-and-price algorithm for constructing an optimal product line using partworth estimates from choice-based conjoint analysis. The algorithm determines the specific attribute levels for each multiattribute product in a set of products to maximize the resulting product line's...

We suggest a scheme to solve a time dependent vehicle routing problem in Bangkok. In fleet transportation, we usually prefer routes aiming to minimize the number of vehicles and the total distance. However, traffic congestion has significant impact on cost and time for transportation. As traffic...

The design and operation of logistic systems is a complex problem of engineering. The optimization of logistic systems and processes is the key factor of the economical operation. There are different methods and tools to support this optimization field. The networking of the logistic systems and...

The Hungarian waste management sector is under transformation now. The new (2012/CLXXXV) Law on the Waste applies such requirements on the household waste collection enterprises that cause restructuring among the players on the waste market. Besides this, the deposit fee system (that are defined...

In the last decade the development of the economical and social life increased the complexity of transportation systems. In this context, the role of Decision Support Systems (DSS) became more and more important. The paper presents the characteristics, necessity, and usage of DSS in...
