General Economic Order Quantity Model for Lot Sizing with Quality Loss and Process Analysis

1995

In this paper a new model GEOQ is proposed to decide the optimal lot sizing in production. The GEOQ modifies the classical EOQ method in several aspects. First it considers that there is always a probability that the production goes out-of-control; then it takes the time the process goes out-of-control as a stochastic quantity; and finally it adds quality loss to the economic models. The quality loss is calculated according to Taguchi’s quadratic loss function. and depends on the process failure models. Therefore, the optimal lot sizing is decided not only by the set-up cost and the holding cost but also by the quality loss during the manufacturing process.

Efecto Bullwhip y restricciones de capacidad productiva en las cadenas colaborativas

2008

El objetivo del presente artículo es profundizar en el análisis de Evans y Naim (1) sobre la relación entre la capacidad de limitada producción y el efecto bullwhip, y actualizarlo en función de las recientes configuraciones de cadenas de suministro colaborativas. Se analizan tres cadenas de suministro con capacidad de producción limitada: la misma cadena de suministro tradicional estudiada por Evans y Naim (1), una cadena EPOS (Exchange Point of Sales) y una cadena sincronizada. Se adopta un sistema de métricas para evaluar los beneficios de los nodos de la cadena medidos en términos de estabilidad de la orden de pedido, estabilidad de los inventarios, y robustez del sistema, y en términos…

New Trend to Evaluate the Management of Companies: An Application of the Methodologies of Radar Chart

2014

The methodology of radar chart arises as an alternative answer to traditional measures on management of companies' activities. How to answer to market disruptions? It is a question solved by this methodology, which allows us to measure the management of each area represented on a radar chart by applying principles of plane geometry. In this methodology, a decision on a management area affects to the result of other areas because it has a multidirectional effect. Its application is carried out on a Spanish company.

ARE BAD JOBS INEVITABLE? A COMPARATIVE STUDY OF AGED-CARE OCCUPATIONS AND TRAINING

2017

As the population ages globally, the care of older adults with chronic disease and physical and cognitive impairment will require a significantly larger and more skilled direct care workforce than currently exists. Many countries have migration policies to encourage workers to leave home and perform this important work. Others relegate the majority of the labor to vulnerable populations including women of color and immigrants. Do these jobs have to be “bad jobs” with poor compensation, few benefits and heavy workloads? This study comparatively examines the demographic composition and extrinsic characteristics of entry-level aged care jobs in select countries: U.S., Canada, United Kingdom, A…

Food Safety Through Application of an E-Learning Platform

2015

AbstractThe paper investigates the effectiveness of a continuing online education course for the professionals, who provides information on the food safety working group from "Lucian Blaga" University of Sibiu, formed by students (specialization: Engineering and Management in Public Food and Agro-tourism), persons looking for a job (unemployed) and people who works in the food industry. Piloting materials was made both face to face and online. The knowledges was measured using evaluation tests after each lesson and through a final assessment test. The results of the promotion rate was over 90%, which indicates a high efficiency in terms of piloting materials adapted by teachers from the "Lu…

Patented and commercialized applications

2021

Abstract The commercialization of high added-value compounds recovery from food wastes deals with several issues such as laboratory research, scale-up problems, protection of intellectual properties, and development of market-destined applications. These issues are described in this chapter wherein a collection of commercially available compounds recovered from food by-products is presented. Verification of market existing products matching with patented processes was conducted using patent applicant name in each case. However, this matching as well as production characteristics may not be correct in all cases, as most companies typically are secretive about their methods of production and …

Multicriteria decision support in a technology competition for cleaning polluted soil in Helsinki

2000

Due to expansion of the capital area in Finland, industrial areas are being replanned for residential and commercial use. The soil in these areas is sometimes contaminated, and must therefore be cleaned before building. In spring 1997 the City of Helsinki and the National Technology Agency of Finland declared a contract-based competition for cleaning the polluted soil of the planned Toukolanranta residential area. Nine proposals entered the competition, and the problem was to choose three best candidates for test-cleaning a small part of the region considered. The winner of the test-cleaning phase will get the contract for cleaning the whole area. The proposals were evaluated based on five …

INNOVATIVE PERFORMANCE AND INNOVATION SYSTEM OF LATVIA

2021

The research andanalysis of strengths and weaknesses of national innovation system is extremelyimportant to successful and efficient innovation support policymaking.Innovation support policies should take into consideration all specifies ofnational innovation system in the country, not being one-size-fits-all. Untilnow, little analysis on the Latvian innovation system was made. The paper aimsto show Latvian innovative performance and to propose factors forwell-functioning innovation system of Latvia. This research gives apossibility to researchers and policy-makers to investigate the mismatchbetween policies and problems and identify policy gaps. KEY WORDS: innovativeperformance, innovation…

Integrating human resource management into lean production and their impact on organizational performance

2011

PurposeThe first goal of this research is to analyse the effects of lean production (LP) on the policy of human resource management (HRM). The second is to determine whether or not implementation of HRM practices associated with LP explains the differences in organizational performance between manufacturing plants.Design/methodology/approachThe paper developed a questionnaire for data collection. Findings are presented from 76 establishments (79.17 per cent of the total sample) that specialise in single‐firing ceramic tiles in Spain.FindingsCompanies that make the most of LP practices are also those that take care to train workers in using these practices as well as improving their employme…
