Case I$*-$ Enhancing Process Efficiency at Al$-$Tayeb Fast Food Restaurant

Al$-$Tayeb Fast Food Restaurant, located in Kuwait City, has been a popular choice for locals and expats alike. Despite its popularity, the restaurant has faced challenges in meeting the high demand during peak lunch hours from $1-3pm.$ This case study explores the implementation of assembly line balancing to improve process efficiency and increase output.

The restaurant's current workflow is disorganized, leading to bottlenecks and delays in order preparation. Employees often perform multiple tasks simultaneously, resulting in inconsistencies in service quality and longer wait times for customers. The management team at Al$-$Tayeb is asking for your team's help to redefine employee roles based on assembly line principles. This involves breaking down the order preparation process into smaller, more manageable tasks assigned to specific stations. Each station will be manned by employees trained to perform their designated tasks efficiently. The tasks involved in a customer order are listed below, along with their time $($in seconds$)$ and predecessors.
