If so, what is the optimal solution? If not, why does not anoptimal solution exist? Show your calculations and answers clearly.b) Does constraint #5 have slack or surplus? If so, which one and how much?c) Up to how much can the coefficient of Y in the objective function increase without changingthe optimal solution? Show your calculations and answers clearly.d) If one increases the righthand side value of constraint #2 by 2, by how much does the valueof the objective function change, compared with that at the original optimal solution? Showyour calculations and answers clearly.e) Up to how much can the righthand side value of constraint #1 be increased withoutchanging the dual value (i.e., the shadow price) of constraint #1? Answers clearly anddescribe reasons.f) If one increases the righthand side value of constraint #3 by 1, by how much does the valueof the objective function change, compared with that at the original optimal solution?

Valencia products makes automobile radar detectors and assembles two models. Laser stop and Speedbuster both models use the same electronic components after reviewing the components required and the profit for each model, the firm found the following linear optimization model for profit, where L is the number of LaserStop models produced and S is the number of Speedbuster models produced. Implement the linear optimization model on a spreadsheet and use. Solver to find an optimal solution. Interpret the optimal solution, identify the binding constraints and verify the values of the slack variables .

A 36,000 square foot office building in Emeryville, California that was 88% leased had a 2023 annual net operating income estimated to be $1,880,000 with gross leases for all its tenants and a three level subterranean parking garage with 180 parking spaces. The 2024 NOI could be increased by all the following, EXCEPT: Increasing the operating expenses by adding additional maintenance staff Increasing the parking income by charging tenants for their employee parking Increasing the occupancy rate of the building by signing leases with new tenants Increasing the rental rates in new leases that are signed for the building

2.) Your business provides technical support for very complex and specialized machinery used by companies throughout the country, and you currently have support centers at 5 locations. However, due to a poor market, you have been forced to close your centers in Houston and San Diego. You will have to relocate all of your technicians in these two centers to your other three centers in Cleveland, Seattle, and Charlotte. Due to the varying costs of living in each city, and travel and retraining times, the cost for relocating an employee varies depending on where the employee is moving. These costs are given in the following table: To: From: Cleveland Seattle Charlotte $5,000 | $7,000 $7,000 $4,000 $6,000 $8,000 Houston San Diego You currently have 40 employees in Houston and 55 employees in San Diego, which all need to be relocated. Cleveland is able to take in at most 35 relocated employees, Seattle can take in at most 32 employees, and Charlotte is able to take in at most 50 employees.…
John is travelling from home in Sydney to a hotel in Perth. Three stopovers on the way a number of choices of towns for each stop only one hotel to choose from in each town, except for Perth, where there are three hotels (J, K, and L) to choose from Each trip has a different distance resulting in a different cost (petrol) (cost is marked by each arc) Hotels have different costs (cost is marked by each node (town)) ● ● ● The goal is to select a route to and a hotel in Perth so that the overall cost of the trip is minimized. Use dynamic programming (forward recursion) to solve this problem by constructing the usual tables for each stage. Stage: 0 (Sydney) 1 Petrol cost start 22 8 12 Hotel cost 70 80 B 80 25 10 2 50 A E 70 30 10 18 8 7 3 50 F 70 70 H 60 8 10 10 4 (Perth) 50 13 K 10 15 L 60 70

eBook Problem 8-21 (Algorithmic) Round Tree Manor is a hotel that provides two types of rooms with three rental classes: Super Saver, Deluxe, and Business. The profit per night for each type of room and rental class is as follows: Room Type 1 Type II Rental Class Super Saver $37 $18 Explain. Deluxe $40 $33 Variable SuperSaver rentals allocated to room type I SuperSaver rentals allocated to room type II Deluxe rentals allocated to room type I Deluxe rentals allocated to room type II Business rentals allocated to room type II Is the demand by any rental class not satisfied? Business Type 1 rooms do not have wireless Internet access and are not available for the Business rental class. Round Tree's management makes a forecast of the demand by rental class for each night in the future. A linear programming model developed to maximize profit is used to determine how many reservations to accept for each rental class. The demand forecast for a particular night is 125 rentals in the Super Saver…
