Question $2$: $($Answer all parts$)$

A four station assembly system is designed to perform four assembly operations at stations $1$ through $4$ after a starting base part has been manually loaded to the synchronous walking beam conveyor. The assembly system has no internal storage between each station.

Each assembly operation involves the attachment of a component to the existing assembly from the previous station. At each of the four assembly stations a hopper feeder is used to deliver components to a selector device that separates components that are improperly oriented and drops them back into the hopper. Properly oriented parts are processed through gravity fed feed tracks to the station heads.

The assembly time, hopper feed rate $(f),$ proportion of correctly oriented components into the feed track $(),$ fraction defect rate $(q),$ probability of a station jam $(m)$ for stations $1$ through $4$ are shown in the Table Q$2$ below.
