Tkds

Tkds is a supplier decision-support system that scores your suppliers on price, delivery, quality, service and capacity together. Each supplier gets a score out of 100 and an A–E grade, with the weak spots named explicitly and a clear answer to what would raise the score the most.

You set the rules: enter criteria weights through pairwise comparisons and draw the target and the acceptable limit for each criterion yourself. The system does not just calculate — it explains the decision, and every scorecard is archived so you can audit later which data produced which result.

What you can do

• A score out of 100 and an A–E grade for every supplier, plus what would raise it the most
• You enter the weights through pairwise comparisons; inconsistent choices are flagged instead of silently scored
• A target and an acceptable limit for each of the twelve criteria, tunable per product
• Add your own fields (order no, invoice no, receiving warehouse) to the order form without writing code
• Foreign-currency orders are converted at the central bank rate of the order date, not today's
• Invalid entries — negative delay, returns above the order quantity, zero cost — are rejected at database level
• Older orders lose weight over time; a new supplier with little data is marked "under observation" rather than ranked unfairly
• Every scorecard is archived, so which data produced which decision stays auditable

Who it is for

• Purchasing managers who must justify a supplier choice, not just make it
• Quality teams that need ISO 9001 supplier evaluation to be documented and repeatable
• Companies buying in foreign currency that want period-over-period comparisons to stay realistic
