Planning and zoning of trading hall

Пропонується комплекс заходів з планування та зонування торговельного залу для подальшого його застосування на підприємствах роздрібної торгівлі, зокрема у мережі супермаркетів "Сільпо". Розглянуто основні типи планування та умови, коли воно вважається вдалим. Надано детальну характеристику зон магазину. Виявлено, що планування та зонування торговельного залу - це складний і довготривалий процес, проте вдалі рішення з цього питання дають значний економічний ефект.It is proposed a set of measures for planning and zoning trading floor for its further use in retail environments, especially in the network of supermarkets "Silpo". The main types of planning conditions, when the use of each of them to be the best is considered. A detail description of the existing shopping areas and describes the features of the location of individual product groups are given. It highlighted the need for utilization installation floor space when determining the efficiency of use of retail space. It was found that the planning and zoning of the trading floor - a complex and lengthy process, but successful solutions of this problem and their implementation can provide significant economic benefits in the form of increasing the number of customers and sales volumes

Selected crosstalk avoidance code for reliable network-on-chip

Abstract With the shrink of the technology into nanometer scale, network-on-chip (NOC) has become a reasonable solution for connecting plenty of IP blocks on a single chip. But it suffers from both crosstalk effects and single event upset (SEU), especially crosstalk-induced delay, which may constrain the overall performance of NOC. In this paper, we introduce a reliable NOC design using a code with the capability of both crosstalk avoidance and single error correction. Such a code, named selected crosstalk avoidance code (SCAC) in our previous work, joins crosstalk avoidance code (CAC) and error correction code (ECC) together through codeword selection from an original CAC codeword set. It can handle possible error caused by either crosstalk effects or SEU. When designing a reliable NOC, data are encoded to SCAC codewords and can be transmitted rapidly and reliably across NOC. Experimental results show that the NOC design with SCAC achieves higher performance and is reliable to tolerate single errors. Compared with previous crosstalk avoidance methods, SCAC reduces wire overhead, power dissipation and the total delay. When SCAC is used in NOC, it can save 20 % area overhead and reduce 49 % power dissipation
