The model developed in this paper differs from models using the lead-time crashing approach by explicitly specifying the source of the lead-time reduction cost (i.e., increasing procurement cost), which allows for analyzing the impact between lead-time reduction and buyerâsupplier interactions.
Skin color - patchy. Patchy skin color is areas where the skin color is irregular. Mottling or mottled skin refers to blood vessel changes in the skin that cause a patchy appearance. Considerations. Irregular or patchy discoloration of the skin can be caused by: Changes in melanin, a substance produced in the skin cells that gives skin its color.
In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is the manner in which an animal routinely casts off a part of its body (often, but not always, an outer layer or covering), either at specific times of the year, or at specific points in its life cycle. Moulting can involve shedding the epidermis (skin), pelage (hair, feathers, fur, wool), or other external layer. In some groups, other body parts may be shed, for example, wings in some insects or the entire exoskeleton in arthropods.
