What is lot sizing techniques?

Static lot sizing methods consist of ordering a fixed quantity or the exact amount of requirements for the date needed. 1. Fixed Order Quantity: This method involves ordering a fixed quantity when the reorder point is reached. The quantity often depends on the supplier-specific constraints.

What are the trade offs when developing a supply chain strategy?

Don’t Just Reduce Costs — Reduce Trade-Offs!

• Total cost (and the lower-level TCO price elements)
• Cash (e.g., working capital or capital asset levels)
• Delivery (e.g., perfect order performance)
• Quality levels.
• Flexibility (in the supply chain or just qualitatively with a service supplier)
• Innovation (which is increasingly information-based)

What is lot sizing problem?

The Capacitated Lot Sizing-Problem (CLSP) consists of planning the lot sizes of multiple items over a planning horizon with the objective of minimizing setup and inventory holding costs. In each period that an item is produced a setup cost is incurred.

What is the definition of trade-offs?

A trade-off (or tradeoff) is a situational decision that involves diminishing or losing one quality, quantity, or property of a set or design in return for gains in other aspects. In simple terms, a tradeoff is where one thing increases, and another must decrease.

What is cost trade-offs in logistics?

Trade-offs are compensatory exchanges between the increase of some logistics costs and the reduction of other logistics costs and/or an increase in the level of customer service.

What is an example of a trade-off?

In economics, a trade-off is defined as an “opportunity cost.” For example, you might take a day off work to go to a concert, gaining the opportunity of seeing your favorite band, while losing a day’s wages as the cost for that opportunity.

What are the trade-offs between four different transit operation cases?

The critical trade-off variables are the road transportation cost (C), the transport reliability (R), transport information system (I), capacity (V), and safety services (S).

What are the logistics costs?

overall logistics costs into three key components: transportation costs, inventory carrying costs, and administration costs. Total transportation costs include costs for both primary and secondary transportation. Primary transportation is the movement of finished goods from plants and vendors to warehouses.

How is logistic cost calculated?

Divide the total transportation costs by the total sales on the transported products to determine the percentage costs for transportation. Include all transportations costs in this equation, such as payroll for transportation staff, fuel use, insurance costs and maintenance costs.

How do you calculate trucking costs?

To calculate the “cost per mile,” divide the cost by the number of miles you drove that month. For example, “fixed costs per mile” is calculated by dividing $2515 (fixed costs) by 8,400 (miles), which gives us $0.30 per mile. Using the same method, we calculate variable costs to be $0.70.

How do you calculate logistic cost per unit?

To calculate this cost, you start with production expenses that include all overheads incurred, materials, staff, and incidentals. You then add to this the shipping costs from the warehouse to the client’s premises as well as your profit margin to arrive at landed cost per unit.

What are the 4 basic costs of transportation?

The total transportation consists of line-haul, pickup and delivery, terminal-handling and billing and collecting costs. To reduce shipping costs, the shipper needs to do the following: Describe line-haul costs by increasing the weight shipped.

What is the cost of transport?

From Wikipedia, the free encyclopedia. The energy cost of transport quantifies the energy efficiency of transporting an animal or vehicle from one place to another. As a dimensionless quantity, it allows for the comparison of dissimilar animals or modes of transportation.

What are the four basic elements of transport?

The four elements of transport are (i) the way, (ii) the unit of carriage, (iii) the motive power unit, and the terminal. (i) The way. Natural ways are cheap and free, and have no maintenance costs unless we try to improve them artificially. The sea, the air, the rivers, and footpaths are all natural ways.

Are wages fixed costs?

Labor is a semi-variable cost. Variable costs vary with increases or decreases in production. Fixed costs remain the same, whether production increases or decreases. Wages paid to workers for their regular hours are a fixed cost.

Is rent fixed or variable cost?

Fixed expenses or costs are those that do not fluctuate with changes in production level or sales volume. They include such expenses as rent, insurance, dues and subscriptions, equipment leases, payments on loans, depreciation, management salaries, and advertising.

How do you calculate fixed costs?

Take your total cost of production and subtract your variable costs multiplied by the number of units you produced. This will give you your total fixed cost.

Are hourly wages a variable cost?

Hourly Wages Can Be Fixed or Variable Costs When you pay only for the number of hours worked on an as-needed basis – which is usually the case when hiring temporary or contract laborers or piece-workers – then it is considered a variable cost.

What are examples of variable costs?

Examples of variable costs are sales commissions, direct labor costs, cost of raw materials used in production, and utility costs. The total variable cost is simply the quantity of output multiplied by the variable cost per unit of output.

Is rent a variable expense?

Fixed cost includes expenses that remain constant for a period of time irrespective of the level of outputs, like rent, salaries, and loan payments, while variable costs are expenses that change directly and proportionally to the changes in business activity level or volume, like direct labor, taxes, and operational …

Variable costs for a manufacturer would include things like direct labor of hourly workers, other wage employees, direct materials, applied overhead, sales commissions, and depreciation under units of production method.

Is electricity a direct expense?

Key Takeaways. Direct costs are expenses that can be directly tied to the production of a product and can include direct labor and direct material costs. Variable costs can also be indirect costs such as electricity for the production plant since it can’t be tied to one specific product.

Is factory overhead a fixed or variable cost?

Some manufacturing overhead costs, which are also referred to as indirect factory costs, are variable. A common example of a variable overhead cost is the electricity used to operate factory equipment.

Are all direct costs variable explain?

Explain. All direct costs are variable by definition since they can be directly traced to the cost object, and thus must vary with the cost driver or volume of output.

How is direct cost calculated?

The direct cost margin is calculated by taking the difference between the revenue generated by the sale of goods or services and the sum of all direct costs associated with the production of those goods, divided by the total revenue.
