A bakery wants to determine how many trays of doughnuts it should prepare each day. Demand is normal with a mean of 5 trays and standard deviation of 1 tray. If the owner wants a service level of at least 95%, how many trays should he prepare (rounded to the nearest whole tray)? Assume doughnuts have no salvage value after the day is complete.

Inventory management in operations management is the process of ensuring that an organization has enough products, raw materials, and components to meet demand.

Inventory management in operations management is the process of ensuring that an organization has enough products, raw materials, and components to meet demand. It involves planning, organizing, and coordinating resources to maintain the right inventory levels to maximize efficiency. 

Here are some inventory management techniques:
ABC analysis: A sorting method that categorizes inventory into three groups: C-products, which have low demand, take up the most space, and cost the most to store. This can help identify products to store more of to keep operating costs low and maintain a healthy cash flow.
Economic order quantity (EOQ): A calculation-based approach that determines the ideal order quantity, minimizing the total cost of ordering and holding inventory. EOQ considers factors such as demand, ordering costs, and carrying costs to strike a balance between inventory availability and cost efficiency.
Demand forecasting: Uses predictive analytics to determine future demand. For example, demand forecasting for MRO stock can help to predict how many of a given part will be used in the upcoming months.
Safety stock inventory: Keeps aside a small amount of stock as a safeguard against the variability of the product in market demand. This helps in preventing loss of revenue, customers, and market share. 

Other inventory management techniques include:
Just In Time (JIT) Method: Makes what is needed at the right time in the required amount. 
Inventory management is a crucial part of business operations because a company's inventory is one of its most valuable assets.

However, inventory can also be a liability. A large inventory carries the risk of spoilage, theft, damage, or shifts in demand.
