Analysis

Cost models and explainers on production, automation and supply chains. Each one shows its arithmetic and says where its answer stops holding.

Reading guide

How the analysis is organized

The articles sit under three topics, and each topic has a reading guide. Take the guide if you want the pieces in a sensible order, or use the full list below if you already know what you need.

Production Economics: cost per good pack, line throughput, changeovers, downtime and packaging formats.
Automation Investment: payback, installed cost, labor savings, utilization, automation level and the post-installation review.
Trade and Supply Chains: imported equipment, quote comparison and contract packing.

How to read a piece

The articles are built the same way, so you can find what you need quickly. Each opens with the decision it helps with and gives the answer right away, before any detail. Formulas sit in plain text blocks you can copy into a spreadsheet.

The worked examples show the arithmetic so you can check it. Replace the inputs with the plant’s own quotes and measured rates before acting on a result. The last section of each piece lists what the model leaves out and when its conclusion stops applying.

Replace the example numbers with your own before you act on any result. The editorial policy explains how the pieces are written and checked.

Three places to start

If you own the budget and are deciding whether to buy, start with Automation Payback, ROI and TCO to see what each metric tells you. Then read The True Installed Cost of Packaging Automation, so the investment figure is complete before you calculate anything.

If you run operations and want more output, begin with Why Faster Machines Do Not Always Increase Line Output, which helps you find the stage that limits the line. Follow it with Small Batches and Frequent Changeovers to see what changeovers take from that output.

If you’re in finance or purchasing and comparing quotes, Comparing Packaging Machinery Quotes on a Like-for-Like Basis puts the offers on one scope. If any offer crosses a border, add Imported Equipment Costs Beyond the Factory Price.

Articles link to each other where one result feeds another, and each ends with three suggestions for what to read next. The same case numbers recur across several pieces, so a figure in one article can usually be traced to its source in another.

Calculators and data pages are in preparation and will be published only after testing.
