Dynamic customer demands impose new challenges for vehicle routing optimization with time windows, in which appear dynamically within the working periods of depots. The delivery routes should be adjusted as soon possible when emerge. This study investigates a collaborative multidepot problem dynamic and windows (CMVRPDCDTW) by considering resource sharing demands. Resource across multiple servi...

Microstructure and corrosion performance of admiralty brass (ADB) and aluminum brass (ALB) alloys after passing different annealing heat treatments were investigated using optical and scanning electron microscope, energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), DC polarization measurements and electrochemical impedance spectroscopy (EIS). The results showed that heat tre...

Process algebras such as CSP or the Pi-calculus are theories to reason about concurrent software. The Pi-calculus also introduces channel passing to address specific issues in mobility. Despite their similarity, the languages expose salient divergences at the formal level. CSP is built upon trace semantics while labeled transition systems and bisimulation are the privileged tools to discuss the...

We are looking a generic solution for the optimized ball passing problem in the robotic soccer which is applicable to different RoboCup leagues and other digital simulated sports games like basketball or ice hockey. In doing so, we show that previously published ball passing methods do not properly address the necessary balance between the anticipated rewards, costs, and risks. The multi-criter...

one of the most important issues in the supply chain management is reducing the bullwhip effect. the bullwhip effect is the increasing of the fluctuation of demands from customer toward supplier in a supply chain. the reasons for this effect and the solution for its elimination are studied by many researchers up to now. one of the main known reasons is variation of the time value of money that ...

Embedded computer systems are subject to a multitude of requirements. These include real-time requirements, that is, such computers must respond to external events within limited time. Many systems, such as satellites and telephone switches, must also operate unattended for long periods of time. They must not fail due to defective software. Modern object-oriented programming languages, particul...

We develop a competitive pricing model which combines the complexity of time-varying demand and cost functions and that of scale economies arising from dynamic lot sizing costs. Each firm can replenish inventory in each of the T periods into which the planning horizon is partitioned. Fixed as well as variable procurement costs are incurred for each procurement order, along with inventory carryi...
