The information required to decide whether the management needs to rent a warehouse is to be determined. Also, the ways in which the linear programming model can be helpful is to be determined. Concept Introduction: When there are more than two variables (behaving linearly) in a problem in which an objective function is to be optimized, the problem can be solved through linear programming. The solution will also indicate the critical and non-critical variables (called constraints). Thus the impact of any variation of the critical constraints can also be assessed.

Expert Solution & Answer

Answer to Problem 1DQ

The inferenceof not taking another warehouse on rent (at whatever rate) can be derived from this model.

Explanation of Solution

Given information:

Three equal to or less than constraints.
The two critical constraints of raw material and labour costs.
Availability of a warehouse at cheap rates.

The management needs to know whether storage space is a binding constraint. It is not, because the intersection of labour hours and raw materials is the optimal solution.

By selecting Cigna Accredo pharmacy that i identify in my resand compare the current feedback system against the “Characteristics of a Good Multiple Source Feedback Systems” described in section 8-3-3. What can be improved? As a consultant, what recommendations would you make?

Scenario You have been given a task to create a demand forecast for the second year of sales of a premium outdoor grill. Accurate forecasts are important for many reasons, including for the company to ensure they have the materials they need to create the products required in a certain period of time. Your objective is to minimize the forecast error, which will be measured using the Mean Absolute Percentage Error (MAPE) with a goal of being below 25%. You have historical monthly sales data for the past year and access to software that provides forecasts based on five different forecasting techniques (Naïve, 3-Month Moving Average, Exponential Smoothing for .2, Exponential Smooth for .5, and Seasonal) to help determine the best forecast for that particular month. Based on the given data, you will identify trends and patterns to create a more accurate forecast. Approach Consider the previous month's forecast to identify which technique is most effective. Use that to forecast the next…

Approach Consider the previous month's forecast to identify which technique is most effective. Use that to forecast the next month. Remember to select the forecasting technique that produces the forecast error nearest to zero. For example: a. Naïve Forecast is 230 and the Forecast Error is -15. b. 3-Month Moving Forecast is 290 and the Forecast Error is -75. c. Exponential Smoothing Forecast for .2 is 308 and the Forecast Error is -93. d. Exponential Smoothing Forecast for .5 is 279 and the Forecast Error is -64. e. Seasonal Forecast is 297 and the Forecast Error is -82. The forecast for the next month would be 230 as the Naïve Forecast had the Forecast Error closest to zero with a -15. This forecasting technique was the best performing technique for that month. You do not need to do any external analysis-the forecast error for each strategy is already calculated for you in the tables below. Naïve Month Period Actual Demand Naïve Forecast Error 3- Month Moving Forecast 3- Month Moving…
