Skyline queries are important in many application domains. In this paper, we propose a novel structure Skyline Diagram, which given a set of points, partitions the plane into a set of regions, referred to as skyline polyominos. All query points in the same skyline polyomino have the same skyline query results. Similar to kth-order Voronoi diagram commonly used to facilitate k nearest neighbor (...

We consider lattice tree-codes based on a latt ice A having a finite trellis diagram T . Such codes are easy to encode and benefit f rom the structure of A. Sequential decoding of lattice tree-codes is studied, and the corresponding Fano metric is derived. A n upper bound on the running time of the sequential decoding algorithm is established, and found to resemble the Pareto distribution. O u ...

Abstract When implementing software for programmable digital signal proces sors PDSPs the design space is de ned by a complex range of constraints and optimization objectives Three implementation metrics that are crucial in many PDSP applications are the program memory requirement code size data memory requirement and execution time This paper addresses the problem of exploring the dimensional ...

This paper deals with the reduction in manufacturing cycle time of a product using line balancing algorithm. The case study was undertaken in an industry that manufactures air-oil separators for compressors. Current state value stream map was drawn to identify the problem areas. The scope of study was limited to the bottle neck stations. The bottle neck stations are dedicated to the production ...

Abstract—Milk is considered as an essential and complete food. The present study was conducted at Milk Plant Mohali especially in reference to the procurement section where the cash inflow was maximum, with the objective to achieve higher productivity and reduce wastage of milk. In milk plant it was observed that during the month of Jan-2014 to March-2014 the average procurement of milk was Rs....

Service companies, especially in the logistics sector during pandemic, are currently very much needed by many people. The increasing demand for package and mail delivery services is day day, must be balanced with service timely to recipient. PT. Pos Indonesia (Persero) Kantor Pemeriksaan (KPRK) Mojokerto 61300 a company engaged courier which has target able provide better customers. However, In...

Abstract: This research is the application of quality control tools within scope increasing productivity packaging department at PT. XYZ. study aims to determine factors causing decline in packing warehouse area. The first step analyze input data using a Pareto diagram. source problems that occur from outside area are four cases, namely Canceled Delivery, Part Received Without Documents, No Sto...

Hospital pharmacy service is a supporting as well revenue center in hospital. More than 90% of hospital services utilize pharmaceutical supplies, and 50% revenues originate from supply management. In the Covid-19 pandemic situation, installation must calculate logistics management medicine correctly. However, based on stocktaking May-July at Puri Bunda Mother Child Hospital, there were stock-ou...

Previous works have shown the eeciency of a new approach for the Genetic Algorithms, the Dual Genetic Algorithms, in the multiobjective optimization context. Dual Genetic Algorithms make use of a meta level to enhance the expressiveness of schemata, entities implicitly handle by Genetic Algorithms. In this paper, we show that this approach, coupled with a new method, Pareto Elitism, leads to ve...
