Data were analyzed using the PLS-SEM approach through SmartPLS4 software.Findings: The result revealed that lean implementation does not leverage production cost reduction as the lean journey requires long-term orientation, which finally leads to valid cost reduction. The moderating role of lean manufacturing maturity was significant and positive in the relationship between lean manufacturing implementation and production cost reduction.Research limitations/implications: Future research should include longitudinal settings as this study is cross-sectional, and future research might put the present model to the test in multiple industries and regions, including a cross-country comparison to improve the generalizability of the findings. Additionally, further studies could extend this study using a mixed-method approach.Practical implications: By offering a holistic perspective, this study expands the existing literature, contributes to knowledge of integrated lean implementation and supports the management in planning their path towards cost-cutting performance.Originality/value: This study answers the inconclusive finding between lean implementation and operational performance in terms of production cost reduction. The study contributes to the body of knowledge and, most importantly, to the practitioners in planning their lean journey.","PeriodicalId":38526,"journal":{"name":"International Journal of Industrial Engineering and Management","volume":"107 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72889753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Squire","doi":"10.3926/jiem.4229","DOIUrl":"https://doi.org/10.3926/jiem.4229","url":null,"abstract":"Purpose: Sustaining healthcare operations without adequate energy capacity creates significant challenges, especially during periods of constrained energy supply. This research develops a clinical and non-clinical activity-based hospital energy model for electrical load prioritization during periods of constrained energy supply.Design/methodology/approach: Discrete event modelling is adopted for development of the hospital energy model (HEM). The basis of the HEM is business process mapping of the hospitals clinical and non-clinical activities. The model prioritizes the electrical load demand as Priority 1, 2 and 3; with Priority 1 activities essential to the survival of patients, Priority 2 activities are critical activities that are required after one to four hours, and Priority 3 activities can run for several hours without electricity.Findings: The model was applied to a small, medium, and large hospital. The results demonstrate that Priority 2 activities have the highest energy demand, followed by Priority 1 and Priority 3 activities, respectively for all hospital sizes. For the medium and large hospitals, the top three contributors to energy demand are lighting, HVAC, and patient services. For the small hospital, it is patient services, lighting, and HVAC, respectively.Research limitations/implications: The model is specific to hospitals but can be modified for other healthcare facilities.Practical implications: The resolution of the electrical energy demand down to the business activity level, enables hospitals to evaluate current practices for optimization. It facilitates multiple energy supply scenarios, enabling hospital management to conduct feasibility studies based on available power supply optionsSocial implications: Improved planning of capital expenditure and operational budgets and during constrained energy supply. This reduces risk to hospitals and ensures consistent quality of service.  Originality/value: Current hospital energy models are limited, especially for operations management under constrained energy supply. A simple to use model is proposed to assist in planning of activities based on available supply.","PeriodicalId":38526,"journal":{"name":"International Journal of Industrial Engineering and Management","volume":"7 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81174365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

De Castro, Anna Ochoa De Echagüen Aguilar, Vicenç Martinez Ibáñez","doi":"10.3926/jiem.4628","DOIUrl":"https://doi.org/10.3926/jiem.4628","url":null,"abstract":"Purpose: Implementing process management methodology through Lean Management and Design Thinking provides a new way to manage surgical blocks, maximize efficiency and adapt to the high variability of demand. This article presents our experience of implementing a set of improvement actions within the surgical process in the context of Lean Healthcare Processes. The project involved a total of 900 healthcare professionals over a 3-year period (2017-2019) and has impacted over 38,000 surgical patients each year at the Vall d'Hebron University Hospital in Barcelona, Spain.The purpose of this article is to present a set of improvement projects within the surgical process and show the indicators that monitor its evolution. These projects have been implemented successfully in a hospital with high surgical complexity and indicate how health care professionals and process engineers can work together as a team to improve healthcare resources.Design/methodology/approach: To evaluate the effectiveness of the actions presented, we propose a series of standardized indicators showing how our findings increase the efficiency of the surgical process. We also indicate Lean projects that can reduce patient waiting times and increase capacity. Below is a management model for the surgical process that considers industrial production criteria such as resource planning, optimizing the use of operating rooms and professionals' time and generating the best surgery combinations.Findings: Projects that have increased efficiency in the surgical block the most have been standardized and converted into a model of action. This is designed to adapt to any level of complexity within the hospital process. The set of improvement projects has been divided into 6 stages: Programming, Material logistics process, pre-surgical stage, intra-surgical stage, post-surgical stage and transversal projects; each affecting a different area of the general hospital (not only the surgical unit). Furthermore, a visual flow chart was designed using the results of the project.Findings from the study have led to a 15% increase in surgical capacity without the need for new resources. The average hospital stay also dropped from 7.2 days to 4.1 days. The flow vision in the care process improves the experience of both patients and health care professionals, who see their participation as part of the whole health care process.Research limitations/implications: the projects were mainly developed at the Vall d'Hebron University Hospital. Although several of these projects have been carried out in other hospitals in Spain by the same team of process engineers, results may be biased when the team provides support within its own process department, compared to when it supports the local team in another hospital temporarily.Another important limitation is that it takes several months to implement and consolidate the improvement projects and demonstrate improved indicators in a sustainable way over time.

Trienggadeng Regency. Pidie Jaya. This research is based on the importance of the network in the ongoing teaching and learning process in the network and computer labs, the network in the lab is currently not managed properly and the distribution of bandwidth is not evenly distributed. To get a good internet connection, it is necessary to distribute bandwidth evenly, which can be done using a proxy router. One of the features for distributing bandwidth evenly in the proxy router can be applied using the simple queue and queue tree methods, knowing network quality can be done using Quality of Service (QoS) measurements. This study aims to determine the analysis of network quality using Qos on proxy routers using the simple queue and queue tree methods. The method used in this study is to use the action research method (action research), the stages of the research are analyzing, data collection, data completeness, making network designs, and taking action. The results obtained for network analysis in a comparative study between simple queue and queue tree networks, the results for the delay obtained by the queue tree are 9 ms, packet loss = 0%, and throughput = 549 k. Whereas the simple queue obtains the value from the QoS measurement by performing calculations with the equation formula to obtain a value of delay = 8 ms, packet loss = 0.15% and throughput = 629 k. Based on the Tiphon standard, it can be concluded that for delay, a queue tree is better with a value above the simple queue with a very good index, the packet loss queue tree is better than the simple queue, the index is very good, the throughput of the simple queue is better compared to the throughput queue tree. This research shows that overall Queue Tree is more optimal for QoS.","PeriodicalId":38526,"journal":{"name":"International Journal of Industrial Engineering and Management","volume":"12 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2023-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87578023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
