the purposes of this research have been to determine the wastewater quality of a typical railroad repair workshop and to find a way to reduce the concentrations of present contaminants especially oil and grease. the mean concentrations of oil, cod and ss in the wastewater studied were 287.69, 775.85 and 28723, respectively with average daily discharge to be 30-35 m3. three successive treatment ...

This paper considers a k-out-of-N system with identical, repairable components. Maintenance is initiated when the number of failed components exceeds some critical level. After a possible set-up time, all failed components are replaced by spares. A multi-server repair shop repairs the failed components. The system availability depends on the spare part stock level, the maintenance policy and th...

This research paper focuses on the simulation-based comparative study of several new dispatching rules with the existing ones for the minimisation of flow time based performance measures such as mean flow time, maximum flow time and variance of flow time. The authors have proposed five new flow time based dispatching rules. The best of existing rules such as PT+PW, AT, AT-RPT, FDD and the stand...

Due to the wide acceptance of web services and its rapid spread, a number of mission-critical systems will be deployed as web services in the next years. The availability and efficiency of these systems has to be ensured in cases of failures and network disconnections. An example of web services for which availability and efficiency will be crucial issue is Auto Repair Service. It is critical b...

Accidental death from postural or positional asphyxia takes place when the abnormal position of the victim's body compromises the process of respiration. Diagnosis is largely made by circumstantial evidence supported by absence of any other significant pathology or trauma explaining death. This case report is about a 50-year-old male who had been drinking the previous night and was found dead i...

Both service and manufacturing industries depend on the availability of expensive equipment to deliver their products. Examples of such equipment include aircraft, rolling stock and manufacturing equipment. When this equipment is not working, the primary processes of their owners come to an immediate stop. To reduce the downtime of equipment, companies stock critical components such that the eq...

The Covid-19 health protocol is a regulation by government to feel safer doing activities during pandemic. Generally, spread of occurs in public places, one which shop. By building an IoT tool that expected be able detect early on the potential for someone contract detecting body temperature and mask when entering store. Shop owners can see people who have customers are wrong/not wearing masks,...

In this thesis, I present several different methods for solving the Car Sequencing Problem. The process of scheduling vehicles along a production line has to take several constraints into account which are defined by the body shop, the paint shop and the assembly shop. I attached importance especially to the paint shop constraints, because no violations are allowed here. Beside the enhancement ...

The paper discusses the role of process and robotics simulation in the automotive industry. Real-world applications of simulation in the body shop, paint shop and general assembly areas of a vehicle assembly plant are given in addition to Business Process Reengineering (BPR) and supply chain logistics applications. Uses of simulation during the different phases of an engineering project are add...
