1. Faster modes of transportation generally cost more than slower modes.Please, continue.

So although shipping on order overseas by airplane is much faster than transporting by ship, it can cost as much as 20 times more. Such a cost difference might not justify the use of the faster way at transporting the goods.

Supply chain manager must therefore carefully consider the cost of transporting goods when determining whether to move product and how to move product in the most economical manner.

2. Transportation systems serve people, and are created by people, both the system owners and operators,who run, manage, and maintain the system and travelers, who use it.Please, continue.

Travelers’ time depends both on freeflow time, which is a product of the infrastructure design and on delay due to congestion, which is an interaction of system capacity and its use. On the upper right side of the figure are the adverse outcomes of transportation, in particular its negative externalities:

• by polluting, systems consume health and increase morbidity and mortality;

• by being dangerous, they consume safety and produce injuries and fatalities;

• by being loud they consume quiet and produce noise (decreasing quality of life and property values); and

• by emitting carbon and other pollutants, they harm the environment.

All of these factors are increasingly being recognized as costs of transportation, but the most notable are the environmental effects, particularly with concerns about global climate change. The bottom of the figure shows the outputs of transportation.

3. Write the formula for annual working hours of car washing and cleaning

where

t_УМР – specific work volume of car washing and cleaning;

t_УМР = 0,2. (hand car wash method t_УМР =0,5; mechanized car-wash method t_УМР = 0,15-0,25),

N_{З. УМР} – number of wash station visits per year

1. Most businesses manage both inbound and outbound logistics. Please, continue.

Transportation provides the flow of inventory from points of origin in the supply chain to destinations, or points of use and consumption.

Logistics: inbound and outbound.

Inbound involves the procurement of materials and goods from supplier location.

Outbound – the distribution of materials and goods to customer location.

2. An effective designing for operations approach will also require direction for the design or project development team on what to consider. Please, continue.

This primer recommends closely linking the design process to the planning process given that the collaborative decision made during the planning process guide consideration. Any objectives and performance measures for transportation system operations should be used in evaluating design alternatives so that the infrastructure support the areas ability to reach its operations objectives. The infrastructure should be designed to support applicable MandO strategies that have been selected through the planning process or throughout the development of an operations strategic plan of a regional ITS architecture

3. Write the formula for calculating the number of car visits of wash station before servicing in a year

(2.3)

where

N_СТО – number of vehicle to be repaired or serviced per year;

d – number of station visits per automobile in a year.
