Effective movement of raw material, semi-finished and finished products plays an important role in successful operation of any manufacturing organization. Material movement from one workstation to another accounts for about 30 to 40% of the cost of final product. Proper methods adopted for material movement are also important for the overall safety of the personnel involved in the manufacturing...

Injuries resulting from medical device use errors far exceed injuries arising from device failures. Until recently, human factors issues have received relatively little attention in medicine. Although the situation is gradually changing, many devices that are currently on the market are suboptimal from the human factors perspective. This situation places significant responsibility for the devic...

Earthmoving operations often involve a large number of specially designed equipment with significant purchasing/leasing prices, high operating and maintenance costs. Hence, choosing the right fleet is a major concern from the construction planners’ point of view. This paper presents a methodology that combines discrete-event simulation and optimization to solve the optimal fleet selection probl...

contractor selection is one of the most important problem in supply chain and itsstrongly effect on firm`s performance. because a significant amount of auniversity`s budget assigns to construction contracts, contractor selection is animportant problem for the financial status of universities. since contractor selectionis a multi-criteria decision making problem (mcdm), lots of methods proposed ...

Vendor selection decisions are complicated by the fact that various conflicting multi-objective factors must be considered in the decision making process. The problem of vendor selection becomes still more compli-cated with the inclusion of incremental discount pricing schedule. Such hard combinatorial problems when solved using meta heuristics produce near optimal solutions. This paper propose...

A decision making process requires the values of conflicting objectives for alternatives and the selection of the best alternative according to the needs of decision makers. Multi-objective optimization methods may provide solution for this selection. In this paper it is aimed to present the laptop selection problem based on MOORA plus full multiplicative form (MULTIMOORA) and multi-objective o...

A robot that is to assist humans in everyday activities should not only be efficient, but also choose actions that are understandable for a person. One characteristic of human task achievement is to recognize and exploit opportunities as they appear in dynamically changing environments. In this paper we explore opportunistic behavior for robots in the context of pick and place tasks with human ...

This paper presents an evaluation study that compares two different problem selection strategies for an Intelligent Tutoring System (ITS). The first strategy uses static problem complexities specified by the teacher to select problems that are appropriate for a student based on his/her current level of ability. The other strategy is more adaptive: individual problem difficulties are calculated ...
