Traditional multi-beam Geostationary (GEO) satellite communication systems provide broadband coverage using a regular grid of fixed spot-beams with uniform 4-colour frequency (4CR) reuse scheme. However, user distribution is non-uniform on ground and, consequently, the demand varies geographically. One potential solution to address high-demand regions enhance beam gain only in those areas. In t...

Purpose: Demand-Driven Distribution Resource Planning (DDDRP) has recently been proposed in the literature to deal with higher supply networks complexity, shorter customer tolerance times, and inaccurate forecasts. The DDDRP requires position inventory buffers critical network nodes, where level each buffer is replenished based on actual demands rather than demand This paper aims identify optim...

The development of the retail market in Ukraine and world requires improvement methods models effective interaction supply demand chain for purchase goods daily demand. article presents an integrated method driven management at distribution stage FMCG (Fast moving consumer goods). influence end-consumers on functioning logistics system has been investigated. approach is based systems analysis, ...

Torque control strategy is a common strategy to control robotic manipulators. However, it becomes complex duo to manipulator dynamics. In addition, position control of Permanent Magnet Synchronous Motors (PMSMs) is a complicated control. Therefore, tracking control of robots driven by PMSMs is a challenging problem. This article presents a novel tracking control of electrically driven robots wh...

Objective:Privatization is considered as one of the most important components of new public management with its pros and cons. However, privatization has been accepted and implemented as a policy in the whole political and economic system of Iran, but the barriers and dysfunctions of privatization policy implementation has reduced its effectiveness and efficiency in solving the problems of the ...

The objective of this paper is to propose a multidisciplinary approach for the analysis of demand and innovation. It combines insights from studies on technology diffusion, evolutionary economics and cognitive psychology to argue that consumption and demand are learning processes driven by trial-and-error, rather than by ex-ante maximization. The paper presents a heuristic synthesis to incorpor...
