Despite the lower operating and capital costs of the MT-POX and ATL processes, elemental sulfur may cause environmental problems such as acid mine drainage, or downstream process operation problems such as low solid/liquid separation efficiency or leaching efficiency.
This was the case even when the young adult described discontinuous interactions with other staff members in the setting, or other process related problems such as long waiting times.
It also avoids process level problem such as residual dependencies [33], process dependency on its original (source) node.
Process issues include problems such as weak ties between industry and academia, the need for trans- disciplinary, inter-level, and multinational collaboration, and incomplete BIM curricula.
This technique is more appropriate than traditional analytical hierarchy process in addressing problems such as the comparison of sub-component alternatives.
The polymers synthesized by this process face the problems such as the inability to precisely control molecular weight and distribution, the limited capacity to make complex architectures, the range of undefined defect structures, and other forms of "structural irregularity".
However, the diversity of the population and exploration capability of the algorithm may deteriorate or may be completely lost through a very small number of generations, i.e., at the beginning of the optimization process, that cause problems such stagnation and/or premature convergence.
But the process has some problems, such as high production cost, low yield, and acidic pollution [ 22].
Besides, its manufacturing process also exists many problems, such as time consuming, low production, polluting environment, and wasting of raw materials.
