The computer laboratory at a State University has a help desk to assist students working on computer spreadsheet assignments.  The students patiently form a single line in front of the desk to wait for help.  Students are served based on a first-come, first-served priority rule.  On the average, 15 students per hour arrive at the help desk.  Student arrivals are best described using a Poisson distribution.  The help desk server can help an average of 20 students per hour, with the service rate being described by a constant distribution.  Calculate the following characteristics of the system: The average utilization of the help desk server. The average number of students waiting in line. The average number of students waiting in the system. The average time a student spends in the system

Inventory Management

The supply chain is crucial to a firm's operations as it manages the inflow and outflow of products that are manufactured from the initial stage to the end product. It also considers the raw materials needed at different stages of production and when the work is in progress. Inventory management functions consist of ordering, storing, and procuring the organization's inventory like raw materials, factors, and finished products. It's also used for controlling the number of products for trade and helps manage the organization's inventory and stock. Inventory Management has been defined as having the right inventory, of the right volume, at the right cost.
