Two workstations are laid out in series. Subassemblies are passed from Workstation 1 to Workstation 2 for completion. It is assumed that there is always a subassembly available prior to Workstation 1 and that there is a buffer between both workstations which can cater for any potential back-log The times in minutes for processing subassemblies at each workstation are as follows: Workstation 1 (WKN1)- U (12, 22) -uniform distribution, Min- 12, Max 22 . Workstation 2 (WKN2) N (15, 2)-normal distribution, Mean 15, Standard Deviation-2 The reliability of each workstation in terms of its ability to produce assemblies within specification is described by an exponential function with failure rates for individual workstations as follows: N WKNI-0.08 WKN2-0.06 Carry out a manual simulation of the system of two workstations in series for up to 40 minutes. Assume the system is in steady state before starting, i.e. there is a subassembly available at each workstation. Ideally, the results of your manual simulation should include: .A presentation of the Event Calendar and its changing nature .A description of the main events and the logic associated with them The number of assemblies produced during the 40 minute production period The number of failures /faults in the assemblies produced in the system during the 40 minute production period Note: You may use a single random number multiplied by 12 in place of 12 individual random numbers to minimise computation time when determining values from the normal distribution.
