While LHT has traditionally performed the MRO services in-house, the subcontracted operations business is gaining momentum.\u003c\/p\u003e\u003cp\u003eWith about 90,000 outsourced MRO purchase orders (POs) per year, the process becomes increasingly complex. In the past, the company set the objective of achieving an average turnaround time (TAT) of five shop calendar days (SCD) for internal repair operations.\u003c\/p\u003e\u003cp\u003eOne of the main goals of LHT is to achieve an average TAT of fifteen SCD for the subcontracted MRO operations, between the monitoring points ¿Creation PO Requisition¿ (i.e.: TS 29) and ¿Receive Unit Transaction¿ (i.e.: TS 69). The current TAT is significantly higher, with substantial process variability.\u003c\/p\u003e\u003cp\u003eThe repair subcontracting value-chain consists of several processes, which fall under different areas of responsibility. Due to the stochastic nature of the series of processes and because\u003c\/p\u003e\u003cp\u003emany variables influence the overall performance of the system, a simulation study needs to be conducted. The present thesis aims to develop an analytical input model for a simulation study in technical procurement.\u003c\/p\u003e\u003cp\u003ePractical relevancy of the research problem\u003c\/p\u003e\u003cp\u003eThe building of the analytical input model and subsequent simulation model is a substantial\u003c\/p\u003e\u003cp\u003emilestone towards the process optimization in the subcontracted MRO operations business.\u003c\/p\u003e\u003cp\u003eThe modeling of processes as an M\/M\/1 queuing system is the first step needed in order to\u003c\/p\u003e\u003cp\u003ei) Simulate the processes and leverage optimization methods from the field of Production Logistics;\u003c\/p\u003e\u003cp\u003eii) Identify whether the application of queuing theory elements for process\u003c\/p\u003e\u003cp\u003edescription and analysis within technical procurement would aid in improving the processes.\u003c\/p\u003e\u003cp\u003eTheoretical relevancy of the research problem\u003c\/p\u003e\u003cp\u003eThe thesis aims at applying already existing elements from queuing theory and statistics to a relatively new field ¿ technical procurement, as to bring a contribution to the queuing science, an interface between queuing theory and practice.[...]\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783656050629\"\u003e\u003ch3\u003eFor a Material-Flow Simulation Study in Technical Procurement\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783656050629","offer_id":39444891795549,"sku":"9783656050629","price":27.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5b6baef9-f63a-488b-8c25-f2576f50d7e9.jpg?v=1777871945","url":"https:\/\/shop.autorenwelt.de\/en\/products\/process-mapping-and-stochastic-input-modeling-for-a-material-flow-simulation-study-in-technical-procurement-von-ileana-constantinescu","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
