A profit optimisation inventory problem is studied for the products whose demand interconnected with per unit selling price and products’ consumption duration as a multiplicative form of impacts logit-function time power function. reduction opportunity purchase offered to retailer against an order quantity-based prepayment schedule. This study identifies when procedure profitable or non-profitable by examining all possibilities optimum quantity under advance discount scheme. Combining...

Nowadays, consumers are more health conscious than before, and their demand of fresh items has intensely increased. In this context, an effective efficient inventory management the perishable is needed in order to avoid relevant losses due deterioration. Furthermore, products influenced by several factors such as price, stock, freshness state, among others. Hence, research work develops model for items, constrained both physical condition degradations. The a multivariate function current...

Lean Thinking has been one of the preferred approaches to improve healthcare processes in developed countries; however, it barely used Latin America. This study presents a implementation Mexican public academic medical center. The goal was reduce time required discharge patients from Internal Medicine Department. non-experimental intervention measured, analyzed, and improved process flow through study, value-added/non-value-added analysis, four-step quick changeover approach. Once changes...

This paper proposes a maturity model (MM) to become smart organization considering Lean as key enabler drive I4.0 adoption. A systematic literature review on and concepts plus adoption models was conducted through the PRISMA method based articles from Scopus Web of Science databases, records official websites (e.g., consulting firms) published between 2011 2022. Identifying relationship comparing models’ relevant characteristics allowed development MM proposal. Although previous research...

Health care is a complex industry in which professionals are facing the challenge of balancing lower costs with better health and quality care. To remain competitive, organizations have promoted use Lean Six Sigma various settings. More than 300 refereed English-language articles about and/or found literature, many reviews been published on this subject.This article characterizes literature by evaluating classifying 22 reviews, based year publication, country, taxonomy, setting, outcome,...

Purpose The purpose of this study is to assess the state at which lean and six sigma (LSS) are used as a management system improve national health Mexico. Design/methodology/approach Cross-sectional survey-research. survey was administered 30 different hospitals across states in These were selected using convenience sampling participants ( N = 258) through random/snowball procedures, including from top managers down front-line staff. Findings Only 16 per cent respondents reported...

Abstract:In order to minimize maintenance cost and improve rural transit vehicles services, a Regional Maintenance Center (RMC) concept was conceived utilized by the Illinois Department of Transportation (DOT) maintain repair within geographical region. The key attributes an RMC is resource sharing between urban during their respective idle time – facility provide vehicle vehicles. Benefits for providers include lower costs better quality. operating higher utilization rates. Previous studies...

Capital investment in physical assets has increased over the years. With increasing complexity and variety of assets, companies are highly dependent on performing at high efficiency levels. Equipment performance become a crucial business factor that led to particular focus maintenance function. Maintenance is frequently perceived as function having poor rate return due difficulties presenting its benefits terms management can understand. The cost quality model allows translating tradeoffs...

Globally, the numerous efforts exerted toward providing basic sanitation services to people have not been sufficient achieve universal coverage. In developing countries worldwide, many policies, strategies, initiatives, and projects on failed, despite important investments. Of several reasons explaining failure, it is remarkable note that such approaches focused mainly improving technology of system without considering human aspects, as user preferences. Moreover, there currently no...

Lean Healthcare (LHC) is a widely accepted approach to improve the quality of care around world. This research compares two studies, which evaluated adoption/implementation LHC in Finland and Mexico, understand how cultural similarities/differences influence implementations. Data were gathered from previous questionnaire-based studies administered healthcare professionals both countries. Statistics (X2, p, Wilcoxon tests) are used compare across topics related adoption, introduction,...

Purpose Literature shows that the economics of early failures in maintenance and electric utilities have not been deeply analyzed. This study aims to focus on quantifying economic impact current transformers total costs. The empirical is conducted a regional transmission division an utility located Mexico. Design/methodology/approach utility's database was accessed collect 219 records. Clustering techniques were used identify from bimodal distribution failures. Confirmatory goodness-of-fit...

This paper addresses the multi-product, multi-period capacitated lot sizing problem. In particular, this work determines optimal size allowing for shortages (imposed by budget restrictions), but with a penalty cost. The developed models are well suited to usually rather inflexible production resources found in retail industries. Two proposed based on mixed-integer formulations: (i) one that allows shortage and (ii) forces fulfilling demand. Both implemented over test instances case study of...

Assignation-sequencing models have played a critical role in the competitiveness of manufacturing companies since mid-1950s. The historic and constant evolution these models, from simple assignations to complex constrained formulations, shows need for, increased interest in, more robust models. Thus, this paper presents model schedule agents unrelated parallel machines that includes sequence agent–machine-dependent setup times (ASUPM), considers an agent-to-machine relationship, seeks...
