- What a Machine That Can Do Two Things Is Worth Premium Turns "it gives us options" into a figure. Prices the difference between choosing an article after the market has shown itself and committing to one before, charges the switching it implies and the capital it costs, and reports which of the articles a flexible machine is sold on actually contribute to the case and which never win in any market the plant expects. What Flexibility Is Worth cost/yr

- Braid Extension, Diameter Change & the Neutral Angle Treats a braid as the mechanism it is: from a starting and finishing braid angle it returns the extension, the diameter it necks down to, the change in enclosed volume, the geometric limit of extension available, and how far the construction sits from the 54.74 degree angle at which a braided tube is neutral under internal pressure. Extension %

- Failed Fabric Roll Disposition Cost: Downgrade, Rework, Cut Around or Return Costs the four ways a rejected fabric roll can be disposed of - sold as seconds, mended and sold at full price, cut around the faults, or returned - and reports which is cheapest and what it costs as a share of the roll value. Cheapest Disposition
- Let-Off Torque, Warp Tension Swing & Take-Up Load Converts warp tension per end into total sheet tension, beam torque at full and empty diameter, and the tension swing a constant-torque let-off produces across one beam - with the specific tension and the fraction of yarn breaking load the setting is using. Total Warp Sheet Tension N
- Loom Changeover Load & the Gain from Sequencing Similar Styles Prices the changeover as a fraction of the batch cycle, compares a random style order against one that groups similar warps into tie-ins, and converts the availability difference into metres and contribution across the shed. Availability Recovered by Sequencing %
- Loom Stop Cause Pareto, Lost Metres & Annual Cost Converts warp, weft and mechanical stop rates per 100,000 picks into stops per hour, weights each by its own mean repair time to build the true downtime Pareto, and prices the result as lost metres and lost margin across the shed. Loom Efficiency from Stops Alone %
- Sectional Warping Sections, Beam Capacity & Maximum Warp Length Divides a warp into sections against the creel capacity, computes section width and ends per centimetre, and sizes the beam: capacity from flange and barrel geometry, the maximum warp length that fits, and how many beams the planned warp actually needs. Sections Required
- Shed Geometry, Warp Strain & Abrasion Exposure Computes the extra path length a warp end travels when the shed opens, as strain at the top and bottom shed lines, checks it against the yarn's breaking extension, and multiplies it by the shed cycles per metre to give the abrasion exposure a construction imposes. Mean Warp Strain at Full Shed %
- Size Box Concentration & Stock Make-Up Works out warp throughput from count, ends and speed, derives the size box concentration that an add-on and wet pick-up together demand, and returns the cooked stock and dilution water the box consumes per hour along with its turnover time.

Add-On Above What the Loom Needs %
- Sizing Add-On, Water Evaporated & Cylinder Drying Load Derives size add-on from wet pickup and size solids, then closes the drying balance: water carried into the cylinders, water left at the target moisture, evaporation rate, steam demand and the drying heat duty behind them. Size Add-On %

- How Many Warp Specifications a Weaving Shed Can Afford Premium Tests every warp specification in a range against the changeovers it forces, because a specification nobody else shares has to be drawn in fresh every time rather than tied in. Reports which of them carry too few metres per set-up to justify their own warp, what merging them into a neighbouring sett would save, and the loom hours it would return. What Merging the Tail Away Saves cost/yr
