Abstract

The pharmaceutical industry has the potential to produce waste water which is categorized as hazardous waste. The operational process of waste treatment has the potential to pose a risk of processing failure. The purpose of this article is to analyze the risks that occur in the pharmaceutical industry wastewater treatment process. This study uses the Analytichal Hierarchy Process (AHP) method. The number of experts used was three people. The results show that there are four main factors that have the potential to produce a risk of failure of wastewater treatment processes such as man, machinery, method, and material. The method factor is the highest risk factor which is around 0.609 with a consistency ratio of 0.08. In addition, the Sub-criteria that have the potential to experience the risk of process failure are the Standard Operational Procedure (SOP) which has not run optimally which is equal to 0.701. Furthermore, in assessing the level of risk obtained, the optimal SOP is run at 0.685. The implication of the application of the AHP method is that a more in-depth review is needed regarding the criteria and sub-criteria used to obtain more comprehensive results.

Abstract

Taxi services involve the number of taxi and demand. A balance is needed for operated taxi and demand, so that the number of canceled order decreases. This system involves taxi and consumers as agents with various behaviors from their agents, then solved using modeling methods. Agent-based modeling is a feasible method used in this study because it can accommodate the properties and attributes of each agent. From the scenario that has been done, the average number of good fleets to operate is 103 fleets, with the canceled order rate is 1.2% and this model proves that the number of operated taxi is sensitive to the number of requests that exist.

Abstract

Hybrid flow shop scheduling is one topic that is often reviewed by researchers at this time. Hybrid flow shop scheduling is the development of problems from pure flow shop. Flow shop problems have one machine at each stage. In this problem, each stage of operation has a machine that is arranged in parallel. This article aims to discuss the issue of hybrid flow shop scheduling at three stage to minimize makespan. Some previous studies discussed scheduling problems by considering setup time. However, such research is generally for the problem of pure flow shop. Therefore, a new algorithm is proposed to solve the problem. The proposed algorithm is developed from the Pour heuristic algorithm. Several experiments were conducted to determine the performance of the proposed algorithm. This study uses ten numerical experiments. This experiment uses the number of jobs varying from 5 jobs to 50 jobs. The results of numerical experiments show that the proposed algorithm has better performance compared to some other algorithms. The proposed method produces an effective solution if it is used to solve problems with a large number of jobs..

Abstract

To succeed in global competition, the proper aquaculture fish farming supply chain must be built. To determine the accuracy of its supply chain, it is necessary to measure it with the right measuring instruments according to its characteristics. Modeling a conceptual framework for measuring the performance of aquaculture fish farming supply chain is carried out by involving stakeholders as respondents. Expert respondents are selected so that the framework is designed appropriately. A deep literature review, a deep discussion, and a questionnaire are used to identify its indicators and sub-indicators that are following the characteristics of a fishery aquaculture supply chain. These indicators and sub-indicators will be structured into a hierarchy, and then an analytical hierarchy process (AHP) will be investigated and rank the weight of indicators and sub-indicators. This paper concludes that this framework can be used to measure the performance of aquaculture fish farming supply chain. Its measurement result can help the stakeholders to prioritize supply chain improvements on important indicators with poor performance.
