How the menu project adds to the labour and equipment bottlenecks: a five-field matrix

The use of sales and single contributions alone to judge the vegetables may spread the high volume of vegetables indefinitely until the prep, a bottleneck, or the loadman loses a buffer at the peak. Over the same period, under the same distribution channel and under the same dish version, the implementable extended matrix includes sales, single contributions, active person minutes, bottleneck equipment occupancy minutes and failure rates. Each of the five fields must have clear denominator and aggregation rules.

Hatco ' s Menu Project article describes the classic matrix ' s classification of vegetables with profitability and popularity, and mentions that the excessive length of the menu increases the availability, training and implementation time. [1] It supports the inclusion of labour and equipment constraints in the context of the operational review, but does not give the five-field definition, illustrative data or specific decision-making in this paper.

Lock and compare borders first

The period should cover operational fluctuations compared to the planned period, such as the same four-week period, rather than the weekend of the dish A and the working day of the dish B. In practice, there are different tasks, such as feeding, taking out or sending out; in order to merge, the price, packaging, weight and calibre of the labour will be proven. The formulation, sales price or process version changes in a series and does not mix directly before and after the change.

Sales are based on net sales completed and of analytical calibre. The cancellations, refunds, gifts, employees' meals and work-remittances are separate items and are not fully sold for the purpose of matching the billings. The size of the same dish, the set and the single point are separated and not combined by a single name.

Individual contributions and total period

The matrix defines a single contribution as a single net sales income less a single change cost. The treatment of taxes, discounts, platform promotions and food packages for net sales revenue and whether the cost of a change includes packaging, platform fees or other sales-related changes are defined in financial advance. The allocated fixed labour and equipment costs are not quietly factored into a single contribution.

Total contributions during period = single contributions x net sales. The single contribution takes into account the economic results of each additional sale and the total contribution over time takes into account the total impact under current sales. Both are retained and not confused with a “contribution” column. Contributions are not equal to net profits, and they do not automatically include capacity and service risk.

Personnel minutes are active hours only.

Proactive person minutes are the actual time for staff to process the dish, such as lead, size, binding, handling, assembly, packaging and cleaning of the dish. Waiting only for the equipment to run and a person to leave to perform other tasks is not counted as active hours but is recorded separately as process time. The employees were unable to wait for other assignments due to congestion and were given a separate “hours of obstruction”.

The two worked for three minutes at the same time, six personnel minutes, but the working hours lasted only three minutes. When one person is in charge of two fully overlapping concurrent tasks, the full personnel minutes cannot be counted in each of the two dishes; the pre-established rules of assessment are used or the paragraph is retained as shared working hours.

Share batch to interpretable drivers

When a pot of basic sauce or a batch of shared foods are available, the whole set of inputs, active working hours, equipment occupancy, qualified output and end-of-life are recorded and distributed on a retroactive basis. In the absence of actual access, the assumptions can be apportioned between the standard use of the formulation and the net sales, but the assumptions are indicated and reconciled with the actual end of the period.

The total amount to be apportioned must be returned to the original batch: the total number of person-minutes to be allocated to each dish does not exceed the actual active working hours of the batch and the total amount of equipment to be shared to each dish does not exceed the actual occupancy of the equipment. The residual, non-retroactive reservation is unassessed and is not subject to the imposition of a zero-sum average.

Equipment minutes broken down by bottlenecks

Equipment occupancy is the time when the process prevents the equipment from undertaking another similar task at the same time, from the actual occupation to release. Whether heating, restoration, cooling or cleaning is included, depending on whether they prevent a pre-defined task. If G32DG, ZL-2K, LG6-1800C or PC-1200x600-FC actually participate in a process, only the physical model, the post and the task have been checked and the occupation is recorded, without reference to unverified parameters.

The minutes of different equipment are not added to the “total equipment minutes” ranking. The impact on kitchen capacity is not equal to 10 minutes for Vegetable A and another 10 minutes for Refrigerated B. The matrix is separate for each identified bottleneck device and compared with the available minutes for the same time period.

The failure rate must first define the denominator

This paper defines failure as the number of copies that have been produced but that have been redone, scrapped or cancelled because of the quality, process, order information or food safety of the dish. The failure rate = the number of copies that have failed has begun to be produced. The order cancelled by the customer prior to production is not included in the denominator but is also included to check sales and capacity.

When a dish is reworked and scrapped, the failure rate counts only one target, but multiple consequences are kept to account for material and labour. Unknown reasons are not forcibly attributed to staff error or equipment, but are retained for investigation. The definition or denominator of a dish is not directly consistent with historical rates.

An example of a fictional double dish

The following are all calculations, not door-to-door measurements, quotations or benefit commitments. During this period, there are fictional four-week canteens, both of which are in the current fixed formula version. The bottlenecks are shown for Vapour E1 and Tray E2, respectively, without adding E1 and E2.

Field	Recipe A	Recipe B.	caliber
Net sales	1200.	600.	Number of completed meals in the same period
Single contribution	18 bucks.	Twenty-six dollars.	Net income less change cost
Total contributions during the period	21,600 dollars.	$15,600.	Single contributions multiplied by net sales
Active person minutes/s	4.0	6.5	The shared batch has been distributed according to the amount received
E1 occupied minutes/s	8.0	2.0	See E1 loads separately.
E2 occupied minutes/s	1.0	3.0	See the E2 load separately.
Rate of failure	24/1224 = 1.96 per cent	30/630 = 4.76 per cent	The denominator is the number of copies already produced

This table shows a higher total sales volume of A and a higher contribution over the period, but it also has a higher single occupancy of E1; and a higher single contribution of B, but a higher rate of personnel minutes, E2 occupancy and failure. It is not possible to announce directly from one column which course is offline. The E1 and E2 periods will also be compared with the time available, peak overlap and queue records.

Let's look at the real stuff and set it up.

The observers record events in the normal production of listed vegetables, not only from the standard formula. Commencement and closure of batches, individual active hours, stoppage hours, occupancy and release of each equipment, qualified output, end-of-life, back-work and access. If the observation is involved in the process, the batch is marked as an intervention sample.

The experiment was to change only a clear set of variables, for example, to adjust the volume, change a parallel step or limit the maximum sales, and preserve food safety, quality and authorized boundaries. At the same time, record whether the bottlenecks were transferred to another equipment, personnel or delivery slot. A low-flowing success does not mean a peak as well.

Decision-making is not limited to promotion or deletion

If a dish has a high sales volume but is used at a maximum of minutes that is close to the bottleneck, it can be limited, adjusted, reprocessed, diverted or established as an alternative, and not blindly promoted. If a menu has a high contribution but has a high failure rate and a high labour rate, it can begin with a process, training, reduction of the applicable shift or continued observation, increasing exposure without a single number being good.

Each decision applies to the food version, duration, channel, duty-bearer, change, safety and quality cessation conditions, expected changes in fields and review points. The menu is adjusted to recalculate with the same calibre and to check whether delays or failures have been transferred to other dishes. The release of minutes or space does not automatically amount to an increase in profits, depending on what the released resources are actually used for.

Reverse random check protection matrix does not become a filling form

The reviewer randomly draws a sales volume, a contribution, a human minute, a period of equipment occupation and a failed object from the matrix, respectively, for the recovery of silver records, the cost of formulae, field events, the point of release of the equipment and evidence of redaction or end-of-life. When any number can only return to oral experience, the module is retained as unverified and does not participate in the ranking.

A reverse check from a shared batch to check whether the sum of the dishes is returned to the total amount of the batch, and a check from a bottleneck to check whether there is an overlap between the individual dishes in the same period. When an error in apportionment or overlap is detected, the full caliber is corrected, not just the one drawn. The matrix version, data cut-off points and calibre changes should be retained.

The review session first looked at data integrity and bottlenecks before discussing menu action. Where data for one dish cover only low peaks, new connections have not yet passed enough shifts or there is still a large amount of unshared batches, the conclusion should be that the observation should be extended or the conditions for application should be limited, rather than mandatory classification in order to meet the four-wire limit.
