Data were obtained from the results of assessment of the experts in food and beverage company in South Jakarta. The rate selection of suppliers was based on several criteria. There was the suitability in some products with the demand for tolerance of 10% about mismatch delivery, 10% of the accuracy of the product delivery, 5% of products quality, 5% of product prices, 5% of the easiness of information or data, and 10% of the problem-solving action. The results show that 40% of suppliers get a warning letter regarding their performance from January to June 2016, 20% of suppliers have already gotten a reprimand directly from the company, 20% of suppliers have been deactivated from the list of suppliers, because they cannot meet the target value which equals to 4,05, only 20% of the supplier can maintain its performance.","PeriodicalId":31095,"journal":{"name":"ComTech","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49489877","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 first experiment used two class targets that were grouped in ‘on time group’ and ‘late group’. The experiment result shows that the proposed method produces accuracy around 85%. The second experiment used three class targets, ‘on time group’, ‘late group’, and ‘very late group’. The experiment result of the proposed method produces accuracy around 80%.

The results of local contrast enhancement using both methods were compared with the results using histogram equalization method. The tests were conducted using two MDCK cell images. The results of local contrast enhancement using both methods were evaluated by observing the enhanced images and IEM values.

Inventory management was done by combining classifications ABC and (Q, R) with Economic Order Quantity (EOQ) model, which was usually used for uncertain demand. With “A” classification of the goods, two model (Q, R) scenarios were made and then simulated with software Arena. From these two scenarios, the results show that both have a tendency to decline, or the stockouts occur.
