asimulation-optimization approach is proposed for replenishment planning andshelf space allocation. the customers’ demand is divided into fixed andvariable demand. each customer follows a given path while shopping in thestore. by dividing the store space into several zones and calculating therelated substantial and random utilities, an analytical equation is proposedfor the probability of zone ...

Most companies focus on matching and beating their rivals. As a result, their strategies tend to take on similar dimensions. What ensues is head-to-head competition based largely on incremental improvements in cost, quality, or both. The authors have studied how innovative companies break free from the competitive pack by staking out fundamentally new market space--that is, by creating products...

The space industry is currently at a significant inflection point. New economies are forming in lowEarth orbit (LEO), driven by miniaturization of technologies and the promise of lower launch costs, which should then allow many of these LEO systems to capitalize on designs incorporating smaller, shorter-lived spacecraft in highly-disaggregated constellations. Meanwhile, many spacecraft at geosy...

The paper analyzes the satellite broadband systems for consumer from the perspective of technological innovation. The suggested interpretation relies upon such concepts as technological paradigm, technological trajectory and salient points. Satellite technology for broadband is a complex system on which each component (i.e. the satellite, the end-user equipment, the on-ground systems and relate...

The Deep Space Terminal (DS-T) was a task that validated the concept of a fully automated, autonomous deep-space ground station. The DS-T successfully demonstrated “lights out”-mode ground-station operations using a Deep Space Network 34-meter beam-waveguide antenna that tracked a NASA deep-space probe orbiting Mars. The DS-T receives, processes, records, and distributes telemetry data to the p...

Aiming at the spatial distribution of food industry and its evolving model, this study carries out research on the change characteristics of inner spatial distribution of food industry in Wuhan City and the growth of scale of urban land use. Taking Wuhan City as example, from the perspective of micro-level, this study adopts analyzing technologies and statistic analyzing methods about GIS/SPSS ...

Space synthetic biology is a branch of biotechnology dedicated to engineering biological systems for space exploration, industry and science. There is significant public and private interest in designing robust and reliable organisms that can assist on long-duration astronaut missions. Recent work has also demonstrated that such synthetic biology is a feasible payload minimization and life supp...

Managing limited display areas is an increasingly challenging task in the grocery retail industry, especially given the current high levels of product proliferation. The decision of how to best allocate and manage shelf space is critical to grocery retail profitability. Moreover, this decision is escalated for initial shelf space considerations at new grocery stores. Without loss to generality,...

Tourism is rapidly developing as a profitable and clean industry in the world. Today, tourists consider urban areas as tourist attractions since, in addition to the body which has its own charm,every space is dominated by an identity. In this descriptive, comparative study, the criteria determining the urban space identity are attempted to be specified through documentary studies. Then, 105 que...
