$1.$ Develop an optimization model and create a linear program in Microsoft Excel using the provided data.

$2.$ Present your results for each individual quarter and for all quarters combined.

$3.$ Offer insights and recommendations based on your analysis to help MediCrystals navigate this challenging situation effectively.

To develop an optimization model and linear program in Microsoft Excel for MediCrystals' capacity optimization, we need to follow these steps:

$**$Hints$***$

$1.$ Define the objective function: The objective is to maximize the utilization of Fabricadas' production capacity to meet the demand for pharma glass products, including those for COVID$-19$ vaccines and other critical vaccines.

$2.$ Identify the decision variables:

$-$ Amount of each product type $($ampoules$,$ vials, cartridges, syringes$)$ produced in each quarter

$-$ Amount of each product type allocated for COVID$-19$ vaccines and other critical vaccines

$3.$ Determine the constraints:

$-$ Production capacity constraints for each product type in each quarter

$-$ Demand constraints for COVID$-19$ vaccine products and other critical vaccine products

$-$ Raw material availability constraints

$-$ Storage capacity constraints

$-$ Minimum production requirements for other critical vaccine products

$4.$ Gather data:

$-$ Production capacity for each product type per quarter

$-$ Demand forecasts for COVID$-19$ vaccine products and other critical vaccine products

$-$ Raw material availability and costs

$-$ Storage capacity

$-$ Production costs and selling prices for each product type

$5.$ Formulate the linear program in Excel:

$-$ Create a spreadsheet with the decision variables, objective function, and constraints

$-$ Use Excel's Solver add$-$in to solve the linear program

$6.$ Analyze the results:

$-$ Determine the optimal production plan for each quarter and overall

$-$ Identify any capacity constraints and suggest recommendations to maximize utilization

$-$ Compare the Plant Manager's and VP of Operations' perspectives on capacity adequacy

Possible reasons for the differing opinions on capacity:

$-$ The Plant Manager may be considering the sudden increase in demand and the time$-$consuming manufacturing process, leading to concerns about meeting the demand.

$-$ The VP of Operations may be considering the overall annual capacity and the possibility of reallocating resources or optimizing production schedules to meet the demand.

Recommendations:

$-$ Optimize production schedules to maximize utilization of available capacity

$-$ Prioritize production based on demand and criticality of products

$-$ Explore options for increasing raw material availability and storage capacity

$-$ Consider outsourcing some production to trusted partners if necessary

$-$ Maintain a balanced supply of products for COVID$-19$ vaccines and other critical vaccines

By developing a linear program in Excel, MediCrystals can make data$-$driven decisions to optimize their production capacity and meet the increasing demand for their pharma glass products while ensuring a stable supply for other critical vaccines.
