Abstract
In this paper, we have developed the uncertain linguistic hybrid weighted distance (ULHWD) measure. We have proved both the uncertain linguistic weighted distance (ULWD) measure and the uncertain linguistic ordered weighted distance (ULOWD) measure are the special case of the ULHWD measure. The ULHWD measure first weights the given arguments, and then reorders the weighted arguments in descending order and weights these ordered arguments by the ULHWD weights, and finally aggregates all the weighted arguments into a collective one. Obviously, the ULHWD measure generalizes both the ULWD measure and ULOWD measure, and reflects the importance degrees of both the given argument and the ordered position of the argument. Furthermore, the ULHWD measure can relieve the influence of unfair arguments on the decision results by using the ULHWD weights to assign low weights to those “false” or “biased” ones. Finally, based on the ULHWD measure, we have proposed a practical method for evaluating the commercial value evaluation of commercial photography with uncertain linguistic information.

Introduction
Commercial photography is the most commonly used in advertising as a means of display of goods, which is different from other Photography categories, such as artistic and commercial dual identity [1, 2, 3, 4]. Commercial photography under the consumer culture has led to the formation of visual consumption patterns and consumer spending than the product itself. Meanwhile, economic development also adds to the commercial photography invisible power. As digital photography continues to mature and involved in today to commercial photography after the impact to commercial photography far beyond people’s imagination. Now, with technology, social progress, from the city we live to the village every day to see a huge number of colorful posters and advertising, history never appeared at any stage will focus on the visual image and so such intensive visual information. We are entering the era of the image. Commercial photography, as born in the business community and has a unique art form of photography categories, it has been more open style and more and more visual representation of the graphic art forms in society today the most impact of a mass media advertising [5, 6, 7, 8, 9, 10].
In the literature, we find a wide range of methods for decision making [11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38]. However, under many conditions, for the real decision making problems, the decision information about alternatives is usually uncertain or fuzzy due to the increasing complexity of the socio-economic environment and the vagueness of inherent subjective nature of human think, thus, numerical values are inadequate or insufficient to model real-life decision problems. Indeed, human judgments including preference information may be stated in uncertain linguistic variables. In order to effectively avoid the loss and distortion of information in uncertain linguistic information processing process, Xu [39, 40, 41] proposed the uncertain linguistic representation and computational model which has a distinct advantage over other linguistic processing methods in accuracy and reliability. All of the existed uncertain linguistic aggregation operators [42, 43, 44, 45, 46] only consider situations where all the elements in the uncertain linguistic variables are independent.
To do so, the remainder of this paper is set out as follows. In the next section, we introduce some basic concepts related to uncertain linguistic variables and some operational laws of uncertain linguistic variables. In Section 3 we have developed some distance measures with uncertain linguistic information and study some desirable properties of the proposed measures. In Section 4, an illustrative example for evaluating the commercial value evaluation of commercial photography with uncertain linguistic information is pointed out. In Section 5, we conclude the paper and give some remarks.
Preliminaries
Let
To preserve all the given information, the discrete term set S should be extended to a continuous term set
In many real-world problems, the input linguistic information may not match any of the original linguistic labels, and they may be located between two of them. In such cases, Xu [47, 48] defined the uncertain linguistic variables and introduced some of their operational laws.
is called an distance between uncertain linguistic
Let
Motivated by the idea of the ordered weighted averaging operator [52], Xu and Chen [51] introduced a type of ordered weighted distance (OWD) measures:
where
and
It is clear that the OWD measures Eq. (5) emphasize the importance of ordered position of each argument
Consider that weights represent different aspects in both the distance measures Eqs (3) and (5), in order to reflect the importance of both the argument
a type of hybrid weighted distance (HWD) measures, where
is called an uncertain linguistic weighted distance (ULWD) between
Specially, if
is called an uncertain linguistic ordered weighted distance (ULOWD) between
Specially, if
From the above definitions, we know that the ULWD measure emphasize the importance of given individual distances, while the ULOWD measure only emphasizes the importance of the ordered position of the given individual distances, it weights the ordered position of the given individual distances instead of weighting arguments themselves. Therefore, weights represent different aspects in both the ULWD and ULOWD measures. However, both the ULWD and ULOWD operator consider only one of them. To solve this drawback, in the following we shall propose an uncertain linguistic hybrid weighted distance (ULHWD) measure.
The uncertain linguistic hybrid weighted distance (ULHWD) measure, where
Moreover, in what follows, we discuss two special cases of the ULHWD measures:
Proof. Let
Which completes the proof of Theorem 1.
Proof. Let
This completes the proof of Theorem 2.
From Definition 6 and the above theorems, we know that:
The ULHWD measure first weights the given arguments, and then reorders the weighted arguments in descending order and weights these ordered arguments by the ULHWD weights, and finally aggregates all the weighted arguments into a collective one. The ULHWD measure generalizes both the ULWD and ULOWD measures, and reflects the importance degrees of both the given arguments and their ordered positions.
In the 21st century, our country’s commercial photography began to get rapid development, but because the commercial photography career starts late in our country, the technical equipment backward, and there is a large gap compared with abroad. As a new industry, many subjective and objective factors make it development is weak in many ways. Reform and opening up has brought the development of economy and people thought liberation, has brought the great development of China’s commercial photography also. Today, commercial photography technology and foreign equipment has no obvious difference, but in the transmission of commodity information and advertising creative still exist very big difference. In the context of globalization, many enterprises to go abroad, more and more foreign firms will come to China. How to meet the needs of international customers, show the development of China’s commercial photography level, promote the great development of the domestic economy is we need to solve the problem. In this section, we present an empirical case study of for evaluating the commercial value evaluation of commercial photography. The project’s aim is to select the best commercial photography modes. Five possible commercial photography modes

Then, we utilize the ULHWD measure to get the most desirable commercial photography mode.
Ordering of the commercial photography modes by utilizing the ULHWD measure
In this paper, we have developed the uncertain linguistic hybrid weighted distance (ULHWD) measure. We have proved both g uncertain linguistic weighted distance (ULWD) measure and the uncertain linguistic ordered weighted distance (ULOWD) measure are the special case of the ULHWD measure. The ULHWD measure first weights the given arguments, and then reorders the weighted arguments in descending order and weights these ordered arguments by the ULHWD weights, and finally aggregates all the weighted arguments into a collective one. Obviously, the ULHWD measure generalizes both the ULWD measure and ULOWD measure, and reflects the importance degrees of both the given argument and the ordered position of the argument. Furthermore, the ULHWD measure can relieve the influence of unfair arguments on the decision results by using the ULHWD weights to assign low weights to those “false” or “biased” ones. Finally, based on the ULHWD measure, we have proposed a practical method for evaluating the commercial value evaluation of commercial photography with uncertain linguistic information. In the future, we shall continue working in the application of the ULHWD measure to other domains [54, 55, 56, 57, 58, 59, 60, 61, 62, 63].
