Arena Simulation of STR Manufacturing Process Dissertation

Arena Simulation of STR Manufacturing Process - Dissertation Example The present research has identified that Thai Hua Rubber PCL is one of the largest rubber producer and exporter in Thailand. Most of the product is concerning a production of rubber, for example, RSS (Ribbed Smoked sheets), RSS Compound (Ribbed smoked sheets compounds), STR (Standard Thai rubber), Concentrated Latex, ADS (Air Dried Sheets). However, focus product in this research would be STR (Standard Thai rubber) for which we see a manifold increase in demand. The research is aimed to identify measure and analyze the main problems in oven and packaging zone of production flow. The solution of the problem and its further validation by using Arena Simulation is also within the scope of this project. In order to improve the production, data was collected from the company’s existing processes and management information systems. The area of focus was the company’s production and quality control processes. Initially, the company’s existing scenario was simulated by u sing Arena Simulation programming method. Then in-depth analysis was conducted to find out the main problem in the production line and a solution was devised based on lean manufacturing methods. Lean manufacturing is the customer focus approach to deliver or supply what customer demands in the desired form and free of defects and in time. It further aims to reduce all types of wastes encountered during production processes that may impede overall productivity and increase costs. Main tools of lean manufacturing include but are not limited to 5S, TPM, 6 Sigma, and Kaizen. The transformation from a non-lean setup to a lean manufacturing system is critical and requires a systematic approach for this transition to avoid any major breakdown.

Precis - Essay Example Enhancement of human assisted migration gives the best solution for preventing the extinction of surviving species in our ecosystem. If the climate change report predictions of 2 to 6 degrees Celsius of warming rate for the twenty century were true, then there would be minimal time for the stranded species to shift to better habitats unless there is human intervention. Many consider it scary and risky to carry and bring these outside species into the communities that they can flourish. While others consider it being a much more risk when the species do not adapt to the new habitats they are taken and also claim the impossibility of moving all the species together to their new ecosystem. If the species were to be left to try and adapt the harsh climates it would lead to more of the species getting to extinction which is a more risk than taking them to better places. Townsend Peterson lead a team at the university of Kansas which created a model which predicts that species turnover due to local die offs and new arrivals will exceed 40 percent in many places due to the harsh climate change. The team took a population of 1870 species of insects, birds, and mammals across Mexico and based their arguments on the projections of the climate changes in the year 2055. This team published their model in Nature in order to give people a clear view of the predictions that have already begun in several areas and take the precautions so as to protect the existing species from die offs for instance, the die offs that have withered juniper-pinon woodlands across the American Southwest. The region suffered from drought in 1950s and again starting several years ago (Douglas ,6). Future predictions can be made by the use of models and since the climate models predict increasingly frequent drought in the Southwest, the species there will either die off or migrate.
