Task $2$: TPS $[\_\_\_\_/15$ Points$]$

Case: The catering service FRESH FISH has five sales locations $($stores$)$ for fish sandwiches in the city centre. The stores receive deliveries of fresh products every day from the central kitchen located at the headquarters. The kitchen operates one shift per day $(8$ hours$)$ from $6$ am to $2$ pm$.$ The maximum production output is $120$ fish sandwiches per hour. A delivery truck transports sandwiches to the stores two times a day, i$.$e$.$ in the morning at $9$ am and in the afternoon at $3$ pm$.$

One shop assistant works in each store and the store is open from $10$ am to $6$ pm each day. On average, $480$ sandwiches are sold per day. The range of products includes $6$ different fish sandwiches. The customers usually order the same amount of each kind of sandwich every day. Nevertheless, several stores accumulate losses since some products are sold out very early in the afternoon whereas others are still in stock when stores are closing.

The owner of the business is dissatisfied with the current situation. He wants to optimize the internal supply chain: from warehouse to production site $($kitchen$)$ to sales locations. Before he started his own business he used to work for a great automotive supplier. Therefore, he wants to adopt the principles of the TOYOTA PRODUCTION SYSTEM $($TPS$)$ and is looking for your advice.
