Inventory models finally made sense once EOQ, reorder logic, and demand assumptions were explained step by step.
Helped me work through PERT/CPM, crashing, and supply chain questions much faster than my lecture notes.
I was stuck on an operations assignment and got clear help with the spreadsheet setup, model logic, and final interpretation.

Inventory & Supply Chain Concept Explanations (WHY)
Each item below is a one-sentence, exam-ready explanation. Live WHY pages are linked; proposed WHYs are included for academic completeness and future expansion.
Inventory Models (Live WHY Pages)
- Why does the EOQ model minimize total inventory cost? — EOQ balances ordering cost against holding cost to find the order quantity that minimizes their sum.
- Why does the Newsvendor Model maximize expected profit? — It sets the order quantity where marginal overage cost equals marginal underage cost via the critical fractile.
- Why do EOQ and Newsvendor models balance cost tradeoffs? — Both formalize the cost of too much vs too little inventory using holding/ordering or overage/underage tradeoffs.
- Why do EOQ and Newsvendor models optimize inventory decisions? — They convert uncertainty and cost structure into a computable optimal policy.
Inventory Models (Proposed WHYs)
- (proposed) Why does safety stock protect against uncertainty? — It buffers demand and lead-time variability to maintain service levels.
- (proposed) Why do service levels matter? — They quantify the probability of meeting demand without stockouts.
- (proposed) Why do reorder points depend on lead time? — Inventory must cover demand during replenishment.
- (proposed) Why do multi-echelon systems require coordinated policies? — Upstream and downstream decisions interact through shared variability.
Flow & Capacity Analytics (Live WHY Pages)
- Why does Little’s Law always work in queueing systems? — In stable systems, average inventory equals arrival rate times average time in system, independent of detailed distributions.
Flow & Capacity Analytics (Proposed WHYs)
- (proposed) Why does the bottleneck determine system throughput? — The slowest step limits overall output.
- (proposed) Why does variability amplify congestion? — Higher variability increases waiting times nonlinearly.
- (proposed) Why do cycle times depend on utilization? — As utilization approaches 1, delays grow rapidly.
Project Scheduling (Live WHY Pages)
- Why do PERT and CPM improve project scheduling? — They identify critical paths and slack, clarifying which activities control completion time.
Project Scheduling (Proposed WHYs)
- (proposed) Why does the critical path determine project duration? — Any delay on the critical path delays the entire project.
- (proposed) Why does crashing reduce project time? — Adding resources shortens activity durations at a cost.
- (proposed) Why does slack indicate scheduling flexibility? — Slack measures how much an activity can slip without delaying the project.
