Academic literature on the topic 'Level of Service Inventory-Revised'

The research interest in multi-variant lean inventory is quite recent and effective general solution methods have yet to be developed. We propose new solution methods to manage multi-variant inventory for a number of scenarios. The mathematical analyses and three theoretical models are developed to calculate the average customer service level for these scenarios.

Drug offenders continue to cost citizens and governments money, while drug courts attempt to rehabilitate offenders and reduce recidivism. The Level of Service Inventory-Revised (LSI-R) is a risk assessment tool used by courts and probation offices to determine needs and risks of offenders, and often determine levels of supervision. The purpose of this quasi experimental study was to determine if there is a statistically significant association between the initial LSI-R scores of offenders entering drug courts and their successful completion of the drug court program. Therapeutic jurisprudence theory, the theoretical framework for this study, suggests that the courts and the law are therapeutic to people and that drug treatment will promote positive behavior changes for the offenders. Data for this study were acquired from a database provided by a Kansas drug court, including initial LSI-R scores, completion records, and demographics of 210 drug court participants. A one-way ANOVA was used to test the hypotheses. Significant statistical results were found, indicating that drug court success was positively associated with the LSI-R score. The study may lead to social change by providing information about participants, most likely to benefit from drug court programs, which will save governments money and make room in the programs for more successful candidates, thus producing more productive citizens in the community.

Visibility refers to availability of information in real-time to requiring actors so that strategy and operations can be monitored, controlled and changed. A symptom of lack of visibility in inventory management is when information in IT systems does not accurately match what is present in the physical inventory. While there are studies in the area of scientific literature documenting reasons for inventory inaccuracy, a literature gap exists for inventory accuracy in relation to service field operations. This study's objective is therefore to examine what reasons are causing lack of inventory visibility in service field operations and which affected KPI are the most impacted by this lack. The study was designed as a case study at an industrial tools and equipment manufacturer, featuring observations and interviews. A visibility assessment approach to extract affected KPI was also applied. The results found that reasons causing lack in service field operations stem from how company IT systems are designed and in how accurately information is entered by employees in said IT system. It further found that a service technicians' years of service influences the inventory accuracy of their van inventory. Unclearly defined areas of responsibility and accountability were further found to contribute to lack of inventory visibility. The most affected KPI impacted were found to be Inventory in % of COGS and Provision in % of inventory, the reasons being that a lack of visibility leads to higher inventory levels and an increase in provisions.<br>Synlighet i en lagernivåkontext syftar till att information skall finnas tillgänglig för berörda aktörer i realtid så att strategier och operationer kan övervakas, kontrolleras och förändras. Ett symptom på synlighetsbrist i lagernivåer är när information i IT-system inte matchar med vad som finns fysiskt tillgängligt i lagret. Vetenskapliga studier har dokumenterat olika anledningar till felaktigheter i lagerinformation, dock existerar ett litteraturgap gällande hur felaktigheter i lagerinformation uppstår i relation till servicefältverksamheter. Syftet med denna studie är därför att undersöka vilka skäl som orsakar brist på lagersynlighet i servicefältverksamheter och vilka KPI som påverkas mest av denna brist. Studien utformades som en fallstudie hos ett industriföretag. Observationer och intervjuer utfördes, dessutom tillämpades en synbarhetsbedömningsmetod för att extrahera påverkade KPI. Resultatet av studien visar att orsaker som vållar brist i servicefältverksamheter orsakas av hur företagets IT-system är utformade och från hur noggrant information bokförs av anställda i nämnda IT-system. Studien fann även att en serviceteknikers år i tjänst påverkar graden av felaktigheter dennes tjänstefordons lagernivåer. Oklart definierade ansvarsområden och ansvarsskyldighet upptäcktes vidare bidra till bristande synlighet i lagernivåer. De mest drabbade KPI konstaterades vara Inventory in % of COGS och Provision in % of inventory, orsakerna till detta är att synlighetsbrister leder till högre lagernivåer och en ökad volym avsättningar.

Currently, many industrial companies generate many losses in their after sales this is generated to an error in the control of inventories and in turn in a mishandling of their assets through their processes, therefore the present research proposes a management model of processes and control of inventories in order to reduce customer losses due to the large number of existing complaints and thus increase sales. Therefore, the process management model, which will contribute to the standardization, optimization and control of its critical processes, and for which indicators, procedures and policies will be proposed for each stage of the process in order to measure its efficiency and effectiveness for correct decision making. With respect to the control of inventories, it is proposed to make a segmentation of the products, which allows the identification of the most important products for the company, to then design a demand forecast model for families of products that will later be individualized considering their factors initial and finally using an inventory management model will obtain the optimal quantity of spare parts order to use in the technical service of the equipment reducing the annual costs related to the inventory.

The purpose of this thesis is to test, via a GPSS simulation, a heuristic developed by B.A. Rosenbaum. The heuristic determines the level of service a customer receives in a multi-echelon inventory system. The system consists of one central Distribution Centre (DC) which is the source of supply for eight Regional Distribution Centres (RDC's), which themselves are the source of supply for customer demand. Service is defined to be the fraction of demand met from on-hand stock at the location where the order is placed. Two distinct sets of tests on the heuristic are performed in this thesis. First, a wide range of parameter values are used in the simulations to test the sensitivity of the assumptions essential in the development of the heuristic. Second, the robustness of the heuristic is examined when different assumptions are substituted in the inventory system analysed. The analysis indicates the heuristic performs fairly well under various conditions. In particular, increasing the order size or reducing the number of warehouses in the system yield calculated values predictive of the simulated results.<br>Business, Sauder School of<br>Graduate
