**2. Products diversity**

Standard living increase of the population has led to the development of new materials and unique services. Those services were hard to be guessed in the past. The diversity of the products is different from one domain to another. All this requires a rigorous planning on waste and resource management in order to obtain some products or to recycle them after end life. The arising problems caused by technological development have begun to affect the life of our planet. This fact has led to the emergence of management measures and decision-making on emerging issues related to the use of this kind of materials, resources, environmental pollutions, and recycling of end-life products.

Passing on to the **complex products** that include a large variety of materials, from PLM point of view, the situation is more complicated. The recycling and the managing of the end life of products are a challenge. We can ask ourselves which will be the costs of a product in reality,

The diversity of industrial products is a very vast domain and includes embedded materials, the products themselves, the equipment that led to their fabrication, the resources used, the

The product life cycle includes three main stages: **beginning of product life (BOL)**, **middle of product life (MOL),** and **end of product life (EOL)**. These stages consist of processes which

BOL is the most complex phase of the product life cycle including conceive, design, prototyping, testing, development, production process elaboration, and manufacturing of the product. In the second phase of the product life cycle, MOL comprises distribution/sales, product use

End of product life is the last stages of the product life cycle. This stage includes retire, dis-

According to the CIMdata Inc. [7], "Product Lifecycle Management is a strategic business approach that applies a consistent set of business solutions that support the collaborative creation, management, dissemination, and use of product definition information" [7]. Integrating people, processes, business systems, and information, PLM supports the extended enterprise [7]. The extended enterprise is a wider entity that includes the customers, the employees, the suppliers, the distributors, etc., who collaborate in the design, development, manufacturing, and delivery of a product to the end user. The PLM concept is focused on six important concepts, as follows: strategic business approach, phases of product life cycle, collaboration within the extended enterprise, unique and timed product data source and consistency, trace-

**Product lifecycle management for "X field"** is a general term to define a type of management within a specific field of work, for a specific product. "X field" is a generic term that is related to a specific industry. Thus, different products require different process developments, resulting the following: PLM for aerospace and defense; PLM for the automotive industry; PLM for the construction industry; PLM for the consumer and retail industry; PLM for the energy, process, and utility industry; PLM for the fashion industry; PLM for the food and beverage industry; PLM for the industrial equipment industry; PLM for the life sciences industry; PLM for the marine and offshore industry; PLM for the oil and gas industry; and PLM for the

The world's increasing production has led to the use of special materials [5, 6] as composite materials and smart materials. These have been created and adopted to solve a number of industry production problems, to replace the traditional materials used for manufacturing process of the products. These were created to improve physical and mechanical properties and were developed to solve the production industry problems.

There are different kinds of products on the market. There are different approaches in the word regarding the classification of the products in the world. An approach can be made following their complexity. We can say that there are simple products, or complex ones, which are assembled by another product. From the point of view of materials which is embedded in products, we can say that some products are from a single material, from two, or from many constituents. From the recycling point of view, at the end of the products' life, the products which are made by a single material are easier to be managed. Unfortunately, these products represent a small percentage of the diversity of existing products. Today the materials' constituents are very vast, and the constituents of the products are composed of many chemical substances. These are combined in order to achieve, at the end, a material with custom properties for certain products.

Another type of the products is represented by a large used, a **product in great demand**. These types represented in generally the goods, which integrate more options to use. The beneficiaries of them have the possibility to have more devices integrate in a single one. From PLM point of view, each of the extra options is traded like single one, and all are integrated in a single one. An example of this can be the smartphones or smarts TVs. Each of them is designed for a specific function, to communicate or to watch and get some information. At the same time, we benefit from clock, internet access, calendar, games, and many programs that help us. Also, it is observed in an abundance of mechatronic products on the market. These products contain mechanical, electrical, electronic, and software components.

Another type of the products is represented by **customized goods**. These are customized for each individual customer. They must meet certain specific personalized requirements. In general for these types of products, the cost price is higher, manufacturing time is increasing, and life cycle is bigger.

Nowadays, the life of the products has been getting shorter. This is due to technological progress and the requirements of today's demanding market. The life of the products decreases because new products appeared and those have replaced the old ones quickly.

Passing on to the **complex products** that include a large variety of materials, from PLM point of view, the situation is more complicated. The recycling and the managing of the end life of products are a challenge. We can ask ourselves which will be the costs of a product in reality, if the recycling costs at the end life of the product are bigger than production costs.

The diversity of industrial products is a very vast domain and includes embedded materials, the products themselves, the equipment that led to their fabrication, the resources used, the auxiliary substances, and materials that contributed to the technological process.
