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.

Question

20.6 114
A Northwest Airlines ticket counter forecasts that 200
people per hour will need to check in. It takes an
average of two minutes to service a customer. Assume
that
interarrival
times
and
service
times
are
exponential and that all customers wait in a single line
for the first available agent.
a. If we want the average time a customer spends in
line and in service to be 30 minutes or less, how many
ticket agents should be on duty?
b. If we want 95% of all customers to wait 45 minutes
or less in line, how many ticket agents should be on
duty?|

A proposal has been presented to the government of Newfoundland and Labrador that would build a new section of highway which would provide improved access for residents of a remote coastal area near Bonavista. The highway would be 16 kilometres in length. The initial proposal called for 7 toll booths, each staffed by an employee. But a subsequent proposal recommended replacing the employees with machines. Many factors must be considered because the intended employees are unionized. However, one of the government's concerns is the effect that replacing the employees with machines will have on the times the drivers spend in the system. Customers will arrive to any one toll booth at a rate of 9 per minute. In the exact-change lanes with employees, the service time is essentially constant at 5 seconds for each driver. With machines, the average service time would still be 5 seconds, but it would be exponential rather than constant, because it takes time for the coins to rattle around in…

The space in front of the window can accommodate only three vehicles including the serviced ones. Other vehicles are have to wait outside this space. Calculate:a. A. probability that an arriving customer can drive directly to the space in front of the windowb. Probability that an arriving customer will have to wait outside the directed space c. How long an arriving customer is expected to wait before getting the service?
Taylor Swiftt works at a call center as an analyst. In her role, she is tasked with data administration and finding patterns in the data generated from all of the customer service interactions that take place. She has been asked to create a visualization of this data so that she can see at what time most service calls come in during the week. What would you recommend that Taylor develop so that her supervisor can see when calls are coming in, live? Choose the best answer from the options available.

Safety regulations require that the time between airplane takeoffs (on the same runway) will be at least 3 minutes. When taking off, the run time of an airplane on the runway is 33 seconds. Planes are on average waiting 6 minutes and 48 seconds for takeoff. On average there are 16 planes taking off per hour. How many planes are either on the runway or waiting to take off? Round your answer to 2 decimal places.
A series of thefts from your pharmacy area have occurred in the last six weeks. The director of security and the head of pharmacy services now require all persons working in the pharmacy department with access to drugs to clock out after their shifts and then go through a security check before leaving the building. Several employees have complained that they should be paid for this time because the security check is for the employer’s benefit. The director of security and the head of pharmacy services have responded that this security check is for the benefit of the employees to ensure that no one is unjustly accused. Is either party correct? If so, which one and why?
