[Scene definition] screw procurement should not be more than price: the TCO algorithm for the terminal plant is based on the actual production scene of the plant, not on the diameter or price of the screw. It is recommended that the purchase price, waste, energy consumption, stoppage and spare parts be first collated, and that a record of the refuelling weight, cleaning time and first eligible time be established. The aim of this step is to establish comparable old programme benchmarks so that subsequent screw changes can be supported by data.

The most easily ignored of the topic is the cost of a single eligible item and the full life cycle. Plants should divide needs such as appearance, size, intensity and odor into necessary and optimized items, and prioritize using customer complaints and internally defunct Paretto. Vendors can make retroactive trade-offs between interoperability, earmarking and cost when there are clear values for product weight, daily production, customer quality caps and allowed stop times.

[Design Focus] The main line of this case is to replace the simple price with TCO and the current cycle. In geometry and materials programmes, gradual compression controls are applied to cut the heat and sufficient corridors are maintained for gas escape; both the inner diameter and wear of the cylinders are integrated into the co-ordinated gap to avoid new screws being dragged by old cylinders. The final solution would also need to be compatible with the wear and tear of the cylinder, the drive, the physical velocity and the current cleaning process, and would not cover up co-operation or process problems with a single high-level material.

The new [comparison-valid] program proposes a minimum of 48 hours of continuous operation, with a 100-mode extraction for each stabilization phase, and records the screw-back load, back pressure stability and daily production. The tests should compare the old programme with the new programme using the same batch of raw materials, molds and sampling rhythms, and also leave the head model, stabilization and long-lived sample groups for ease of comparison. If only the first one is checked, it is easy to miss the risks associated with heat drifting, material stoppage, reversal loop return and prolonged wear and tear.

When the [stabilized production] spiral is shaped, the temperature protection time for cold-starting and the permitted twist should be set to avoid cold-temperature forced storage, and the maximum number of repairs should be set for each drop and surface thickness recorded for the refurbishment. The time of storage, back pressure, screw velocity, noise and mass of the product shall be recorded in a uniform manner in the shift. When the above indicators change at the same time, the mechanical gaps and the state of the raw materials should be checked before the process is adjusted to avoid the use of parameters to compensate for hardware degradation.

The [integrated cost] cost statement should not only be a screw price, but should also account for test simulators, cleaning materials, transitional materials and bad goods at real procurement prices, as well as quantifying on-site vendor support, spare parts delivery and failure analysis response times. It is recommended that the cost per 10,000 eligible items be exported simultaneously, the cost per 1,000 operating hours and the estimated number of return months. When new programmes reduce waste, refuelling or sudden shutdowns, higher initial inputs are often offset during production.

The [Closed Ring Management] will eventually include drawing numbers, screwdriver materials, heat treatment, critical dimensions, portable tubes, process windows and acceptance data in the curriculum vitae cards. It is recommended that a reference set of data be maintained before and after maintenance to determine wear and tear trends, and that a maximum number of repairs be set for each removal and surface thickness recorded for the refurbishment. When there is a significant change in the feedstock formulation, retrospective ratio, product structure or target node, the applicable boundary of “snatch procurement should not be more than price: TCO algorithm for the terminal plant” should be reassessed, rather than defaulting that the old conclusion is permanent.
