The document outlines a case involving **Red Brand**, a company that cans tomatoes and other products. It describes a meeting among key personnel to decide on production plans for the upcoming season, focusing on using a recent tomato crop. 

Key details:
1. **Tomato Quality**: 20% of the crop is grade "A" (higher quality), and the rest is grade "B".
2. **Capacity Constraints**: They can only produce up to 800,000 pounds of whole canned tomatoes due to quality constraints, and the rest will be used for juice or purée.
3. **Demand Forecast**: The company expects to sell all the canned products but has limitations on the demand for tomato juice and purée.

### Your Questions:
1. **800,000-pound limit**: Daniel Pérez mentioned that production of whole tomatoes is limited due to quality constraints. Whole tomatoes require a minimum quality score of 8, and only a portion of the available tomatoes meets this requirement.
2. **Arturo Cortez's Suggestion Flaw**: His suggestion to use the entire harvest for whole tomatoes overlooks the quality limitations. Not enough tomatoes meet the necessary quality standard for whole tomatoes.
3. **Carlos Diaz's Cost Calculation**: Diaz recalculated the costs by considering both quality and quantity, deciding that it was more efficient to use the lower-quality tomatoes for purée and a mix for juice. His suggestion, however, may overlook potential market conditions or operational constraints.
4. **Goal Programming Model**: You can formulate the model by setting two goals: maximizing the use of tomatoes for whole products (goal a) and limiting the production to 800,000 pounds as suggested (goal b).
5. **Conflicts in Goals**: There is a clear conflict between maximizing whole tomato production and adhering to the quality limitation of 800,000 pounds, making it unlikely to meet both goals simultaneously.

Let me know if you'd like help formulating the programming model in more detail.

### Expanded Questions:
1. How is the contribution margin affected by producing different tomato products?
2. What is the role of quality in deciding product allocation in the canning process?
3. How could Red Brand manage the balance between maximizing production and quality?
4. What methods can be used to improve the quality of lower-grade tomatoes for better use?
5. How could the company optimize its production schedule to meet both quality and demand constraints?

**Tip**: When dealing with resource allocation problems, always consider setting constraints based on both quality and quantity for the most efficient outcome.

Why did Daniel Pérez say that the total tomato production is limited to 800,000 pounds, and what is the issue with Arturo Cortez's suggestion to use the entire harvest for whole tomatoes?

Explore a goal programming model to allocate tomato production at Red Brand, addressing the 800,000-pound limit for whole tomatoes and analyzing Arturo Cortez's proposal in terms of production efficiency and quality constraints.
