Decision Support System in Environmental, Health and Safety (DSS-EHS) Management Systems

摘要

This study was conducted to primarily develop a decision support system in the form of a system software that could integrate environmental, health and safety management systems using an embedded mixed method of research. Such system was named as Decision Support System in Environmental, Health and Safety Management Systems (DSS-EHS). Using the Modified Waterfall Model, with IT experts and end-users as respondents, the study analyzed the present practice of engineers in a certain company in preparing and evaluating information be analyzed in terms of environmental, and health and safety of every project job order they acquire. It also described the solution to the problems of the existing system based on the provisions of International Organization for Standardization (ISO), specifically 14001:2015, and 45001:2018, and the integration of environmental, health, and safety management systems, and capability to print environmental, health, and safety reports. In addition, the design and development of the DSS-EHS was described using the help of the IT experts. Lastly the developed DSS-EHS was described by the end users in terms of functionality, reliability, usability, efficiency, portability, and maintainability. Based on the findings, the present environmental, health and safety management systems of the subject company needs a computer system that could aid it to facilitate easier storage, retrieval, and update of documents pertinent thereto. Also, an integrated EHS Management Systems can improve the accuracy and efficiency of the present system of the subject company The DSS-EHS can be designed with high sufficiency in terms of hardware, software and templates needed for every project job order. It can be developed based on the standards for coding and simulation and could aid to facilitate easier storage, retrieval, and update of documents pertinent in terms of functionality, reliability, usability, efficiency, portability and maintainability.
