Bibliometric data was retrieved from Web of Science core collection with a well-defined strategy. The data was processed using Network Analysis Interface for Literature Studies Project scripts. Subject-wise and year-wise research trends were presented. The shifting concerns in RM in terms of topic, method, and domain were highlighted using keyword analysis. In general, RM showed an increasing number of published papers with exponential manner every year. The research core in RM covered the three major decisions in RM including pricing, quantity control, and structural decision. It was highlighted that RM’s concern has shifted from single-firm decision to be more consumer- and competition-centric. The data showed that the needs of empirical study and more advanced quantitative methods for complex and real-time problems were urged. In addition, the adoption of RM was extended for industries with semi-flexible capacity. The top influential publishers were Decision Sciences, Operations Research, Management Science, and Management Science Manufacturing & Service Operations Management.","PeriodicalId":34167,"journal":{"name":"OPSI","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69282255","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}

The method used was descriptive analysis and moving average forecasting of historical data on the use of prostheses. From the results of the descriptive analysis, it was found that the most common types of the prosthesis were under the knee prostheses and the types of prostheses that mostly used imported components were finger prostheses and prostheses that have been developed locally which were lower and upper knee prostheses and also Syme. The results of the prediction of the number of prostheses showed a stable trend and tended to increase slightly with the MAD error rate of 2.375 and MSE of 10.378 and MAPE of 36%. With this accuracy, the results of the forecasting can be used as a reference for the hospital to make supplies of prosthesis components in the next period so that the time for making prostheses can be shortened.

Shoes have become the primary need of urban communities because of their function that cannot be separated from their daily activities. Shoes that are purchased by consumers are usually packaged in cardboard boxes that follow the components of the contents, namely the shoes and accessories inside. In this case, shoeboxes with the right design and function according to consumer preferences will reduce the likelihood that the shoeboxes are thrown into the trash. Although it is not the centre of consumer attention, shoe boxes remain a necessity in the final production process. It is necessary to design and develop a shoebox product that is in accordance with the final function of the shoebox according to consumer interests. This study uses the QFD method which produces quality 1 houses with communication tools in the form of a preliminary questionnaire to 30 respondents and a follow-up questionnaire to 100 respondents. Concept selection was carried out on the eight alternative concepts developed. The shoebox concept chosen to take into account the desires of the consumer will be made with a sporty shoebox standard size of 22.5 x 12.3 x 32.5 cm. The environmentally friendly shoebox can be seen through the installation of plastic straps which are expected to reduce the use of single-use plastics. In addition, the shoebox is made with an innovative design so that users can use it repeatedly as shoe storage or multipurpose box.","PeriodicalId":34167,"journal":{"name":"OPSI","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46034864","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}

PO XYZ have an experience in reduced consumer satisfaction and with the competitor rise the passenger turn to another competitor. Because of this, it is necessary to conduct this research, for winning customer PO XYZ heart by listening passenger desires. This research used Quality Function Deployment (QFD) which only reached the second phase. Data collection through open passenger questionnaires. In the first phase, product planning, it was found that cleanliness of the bus was a major factor that had to be addressed by PO XYZ of 9.477%. The first phase output in the form of technical characteristics becomes the second phase input, namely design planning. In the second phase four suitable service design alternatives were made. Of the four design alternatives, a third service design is obtained which is the choice with a value of 4.74 from scale 6. This shows that the third alternative service should be implemented as an effort to improve quality in meeting passenger satisfaction of PO XYZ.","PeriodicalId":34167,"journal":{"name":"OPSI","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47650585","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}

Experiencing an accumulation of raw materials when product demand decreases and there is a shortage of raw materials when product demand increases. This study aims to determine a probabilistic inventory model that is good for determining the order quantity, ordering time and safety stock by considering the minimum total cost.
