In service sector, there are challenges in keeping an optimum balance between customers' demand and availability of resources. This problem is going to be more intense in the health sector due to the fact that both arrival and service times are random. Therefore, designing the service environment by keeping the optimum balance between customers’ demand and available resources is becoming a seri...

A path-planning method based on a combination of the static global and the dynamic local pathplanning methods is proposed for robot path planning under a complex environment. There are known static obstacles and unknown dynamic obstacles in any complex environment. The local-path planner dynamically generates a local path using obstacle-motion prediction and a rolling window for dynamic path pl...

With the introduction of the CICS Open Transaction Environment (OTE) architecture introduced with CICS Transaction Server 1.3, we now have much more flexibility for CICS to exploit more CPU engines without the need to split a single region into multiple regions, with the added benefit of reducing CPU consumed per transaction. The implementation of this architecture is fairly simple, but imprope...

This paper investigates the single period inventory Newsboy problem in a general uncertain environment. Here it is assumed that the uncertainty appears in the market demand of the product. Uncertain demand is used to describe a subjective estimate (not estimated by random/fuzzy demand), linguistically expressed by ‘‘demand is about n’’. Using identification functions of the uncertain variable w...

Recently, the use of RFID(Radio Frequency Identification) for object identification is used more often, but the tag collision problem by the use of a radio frequency still exists. Therefore, in this paper, we analyzed tag identification time to minimize tag collisions and improve tag identification time by applying various tag anti-collision algorithms in the suggested method. As a result, we d...

Autonomous navigation of mobile robots in an uncertain and complex environment is a broad and complicated issue due to a variety of obstacles that mobile robots have to detect and represent in their maps to navigate safely. The objective of the navigation-mobile robot is to obtain an optimum path, meaning that the robot should plan a reliable path between the source point and the target point w...

Path planning related to mobile robots is the construction of the collision free trajectories that direct robots towards their goal. In this paper, a bio inspired approach based on the foraging behaviour of the bacteria (E-coli) has been proposed to design an optimal path for the robot. The present approach admires that the mobile robot is capable of reaching the goal by following the optimum p...
