Codeword Codeword is a medium-size firm that designs and manufactures electronic systems for the mass transit industry. It competes with other firms to win contracts to provide such systems. When Codeword receives a contract, it creates a project to complete the work. Most projects range from $10 million to $50 million in cost and from one to three years in duration. Codeword can have 6 to 12 projects going on at any one time, in various stages of completion—some just starting and others finishing. Codeword has a handful of project managers who report to the general manager; other people report to their functional manager. For example, the electronics engineers all report to the manager of electrical engineering, who reports to the general manager. The functional manager assigns particular individuals to work on various projects. Some people work full-time on a project, whereas others split their time among two or three projects. Although individuals are assigned to work for a project…

Mo. The I Love Operations Management (ILOM) Conference, a major international conference, is staffed by student volunteers. One of the tasks of the student volunteers is to register conference attendees. The registration process involves confirming that fees have been paid, retrieving a conference package specific to that person (filed under their last name), and passing on relevant information about the conference. In 2023, conference registration will be handled by a group of 10 student volunteers who work in five pairs to register the attendees (i.e., each pair will together register one attendee at a time). Attendees line up in a common line to be served by the next available pair of volunteers. Attendees arrive at an average rate of 139 per hour (assume Poisson arrival distribution) and the service time is, on average, two minutes (following a negative exponential distribution). What is the average time needed to register (includes waiting and registering), in minutes (round…
